I was wondering if the wobble of a star can determine how many planets are actually in a solar system? Would sunspots possibly due to wobble from planets also determine how many planets were in a solar system? Could solar flares also determine how many planets would be in a solar system as well due to the wobble possibly causing the solar flare eruptions to occur more often than if planets were not present?
Probably because they're tired of the gibberish you write. You aren't interested in real science; only technobabble and whatever buzzwords you've picked up online. It doesn't appear you know the difference. You've displayed no interest in learning from those who do have the answers. When people do answer: if you don't ignore the answers, you argue with them or tell them they're wrong. The only things you accept are those that fit your preconceived notions — whatever those are.
Magnetic Fields are what cause Sun spots and, I believe, Solar Flares. Or, at least, flares often follow magnetic field lines, across the Sun's "surface." Planetary wobbles are mostly caused by gas giants, I suspect. I'm pretty sure rocky planets like the Earth aren't capable of creating such a disturbance. But all of these facts - and more - are most easily obtained on The Internet.
Things like gravity and mass cause a star to wobble from a planet's orbit and there's no threshold where it happens and doesn't happen. Every bit of mass around a star is going to cause the wobble, but larger planets like gas-giants just happen to cause a larger more observable wobble, any wobble generated by smaller planets would likely be too small to detect.
^Most wobbles we see in stars are caused by objects in the Jovian/Superjovian size range orbiting at any given distance from it, yeah. I think, at the moment, we're only just able to notice if something Earth sized is even present at all in a small number of cases. But discerning how many planets, how big, how far out? not a thing.
If I'm not mistaken knowing about smaller planets in an extra-solar system is done by observing the planet as it passes in front of its host star, creating a shadow (an "eclipse", if you will.) And we're only able to *just* do this. Any "wobble" caused by the planet isn't going to be very detectable and, naturally, overshadowed by a wobble caused by the larger planets in the system.
For Jedi, who sleuthed the secret of the Language of the Sphere! English to Czech to Greek to French to "English" In this way, a number of observations are made of the spectrum of light emitted by a star. Periodic changes in the spectrum of the star can be detected with a wavelength characteristic spectral lines in the spectrum of rising and falling regularly over a certain period of time. Statistical filters are then applied to the data in order to cancel the effects of spectrum from other sources. Using mathematical best-fit techniques, astronomers can isolate tale periodic sine wave that indicates the planet's orbit. [6] If detected extrasolar planet, a minimum mass for the planet can be determined from changes in the radial velocity of the star. To find a more accurate weight measurement requires knowledge inclination orbit of the planet. The graph of the measured radial velocity versus time gives the characteristic curve (sine curve in the case of a circular path) and the amplitude curve allows the minimum mass of the planet is calculated. Bayesian Kepler periodogram is a mathematical algorithm that is used to detect one or more exoplanets of successive radial velocity stars that are in orbit. This includes Bayesian statistical analysis radial-velocity using the prior probability distribution over an area designated by one or more sets of the Keplerian orbit parameters.
The usual term is transit. Other planetary detection methods are listed here: http://planetquest.jpl.nasa.gov/page/methods The smaller the planet and the farther the distance from its star, the harder it is to detect, which is why we've mostly detected a lot of hot gas giants around red dwarfs. Periodicities in solar flare occurrence have been measured (see, for example, http://sun.stanford.edu/~bai/period.pdf). One interpretation is that there is an oblique magnetic wave pattern with a period of 25.5 days that rotates around an axis tilted at an angle of 40 degrees to the Sun's axis of rotation. The exact cause remains unknown but the mechanism is thought to be due to processes of differential magnetic field winding within the Sun's convection zone rather than to gravitational effects. The period is close to the sidereal rotation period (24.47 days) of the Sun at the equator. Using helioseismology, we know the rotation profile of the Sun at different depths and latitudes quite well. https://en.wikipedia.org/wiki/Solar_rotation#Internal_Solar_Rotation https://en.wikipedia.org/wiki/Helioseismology#Internal_structure
I'm glad Dryson asked this question. I certainly was unaware of some of these facts. It's interesting, actually ...
You are vaguely referring to Jedi Master's post from TNZ to have fun by trolling somebody instead of contributing. By doing this you were trying to make everybody laugh about the person this is trying to parodise. You broke 2 rules: 1) What happens in TNZ stays in TNZ. 2) Don't troll people. It was a deliberate attempt to make fun of a person without that person knowing. I went back and forth on this because you're usually not one to cause issues but you broke two very important rules so I can't help but hand you an infraction. Comments to PM.
Yup, trying to determine the size of small objects passing between the star and our telescope. So far as I know, it takes something substationally large in a solar system to make a star move even the smallest amount. Working out how many planets are in the system would have to be done by a number of different techniques, if possible at all. Earth may not be visible in any meaningful sense that far out from our own system, no matter how much 1960's invasion movies said otherwise.
Earth-like planets could be imaged by using the Sun as a gravitational lens from a distance of 550 and more astronomical units - that's about 1% of a light year (1 ly = 63241.1 AU). Electromagnetic energy from the object being observed is potentially amplified by a factor of 100 million times. http://www.centauri-dreams.org/?p=785
Even a small amount of gravity from another planet could effect the flares and sunspots on a sun. If we have a large body of water representing the sun that is smooth and were to bring a helicopter representing a planet like Jupiter close to its surface maybe 50 feet the turbulence caused by the downdraft would cause the surface of the body of water to be effected. https://www.quora.com/What-is-the-e...odies-affect-Earths-orbit-and-the-Suns-motion Based the article in the link above all of the planets of a solar system would affect the sun they are orbiting with the larger planet creating more surface turbulence with the smaller planets causing lesser turbulence. Now let's wrap our large body of water into a sphere and set the helicopters downdraft at a velocity comparable to each planets gravitational field along with relative distances from the sun that the planets are where the downdraft would represent gravity. Each helicopter would then turned on and the effect of turbulence measured. The data would then be used to compare surface turbulence of each type of planet with solar flares and sun spots on a sun given the solar flare and sun spots location on the sun compared to where each planet was when the sun spot or solar flare occurred.
Those two situations aren't even remotely similar. Apples and oranges, dude. Plus, what Chemahkuu said just above.
Well, obviously. Look at the sun through a fan blade or a helicopter blade and it will appear to wobble. Eureka! It make perfect sense!
Its obvious that it is not me who is posting meaningless dribble. The comparison was meant to demonstrate how gravity in the form of a downdraft would effect the surface of the sun that would otherwise be unaffected like the smooth surface of a large body of water. In science you have to be able to create easily understandable comparisons that can be tested by all to produce the desired result. If a planet like Earth is present it will cause a reaction to take place across the surface of the sun because of the gravity of Earth pushing against smaller planets between the Earth and Sun. According to Einstein's theory of relativity, gravity is not pulling us down but space is pushing us down. When something is pushed down it creates an indentation. When gravity pushes something down that is otherwise a smooth surface turbulence takes place.
