spectral class of m1 and/or pleiades?
546706
Spectral classes refer to INDIVIDUAL stars. The Pleiades is a cluster of several stars, and M1 is the Crab Nebula.

T Tauri stars have bipolar outflows, to the best of my knowledge.  They form Herbig-Haro Objects when the collide with slower matter from the interstellar medium.  They might not always show up with T Tauri stars because of nearby nebula, but my astronomy professor (James Kaler, UIUC) assures me that they are there.\n\nIf you're talking about mass outflows that the T Tauri stars outputs in addition to the bipolar flows, then I'm sure Doppler shifting can be used.  The speeds for the regular outflows should be pretty similar to that of the T Tauri itself, whereas the bipolar flows (depending on orientation to earth, of course) should be much higher.  I hope this helped!

Hi. A good one might be Regulus because it lies pretty close to the ecliptic and is very bright. But you can use any star. For much better accuracy scientists use quasars due to their vast distance. This eliminates parallax error.

By using spectra. Each element has characteristic frequencies of light that it emits or absorbs. If light from the star is spread out into a spectrum (like a rainbow), there will be dark lines for absorbtion and bright lines for emission. By identifying the chemicals that correspond to those lines, we deduce the composition of the star.

The visible series is also called the Balmer series. The energy transitions are from n>2 to n=2. The least energetic and hence longest wavelength line would be the transition from n(h)=3 to n(l)=2. The equation is: \n\n1/lambda = RH (1/n(l)^2 - 1/n(h)^2) \nFor RH use Rydberg constant of 10972130 m^-1 (or .010972 nm ^-1), n(l) is 2, n(h) is 3.\nSolving gives lambda = 656nm, this appears as red.

look here:\n\nhttp://neo.jpl.nasa.gov/cgi-bin/neo_ca\n\nselect what you want to see displayed from the pop-up menus and select display table.  try selecting "PHAs (Potentially Hazardous Asteroids)" from the first pop-up menu.

It is not a star but a planet which you can tell since it is not twinkling. Stars are so far away they appear as a point, while planets have a observable disk. Wind in the upper atmosphere then causes the light to bend which causes star light to twinkle but planets do not. \n\nOnce you determine it is a planet because it is not twinkling. You can rule out it being venus since it is too far from the sun. Venus is also usually a bit brighter.\n\nNow it is too bright to be Saturn or certainly any further planet. That leaves Jupiter or Mars. These you can distinguish by color. Mars has a reddish tinge to it. What you are observing does not.\n\n It is Jupiter. If you have a good pair of binoculars you should even be able to make out a couple moons.
