I know that in spectroscopic Binaries, you can observe wavelength shifts in each star. But how do you determine the total radial velocity of this system alltogether, and how do you find each star's radial velocity?

i have been trying to do this problem for an hour and i have no clue what to do for it... please help me It's on the 4th page down and it is called "Spectroscopic eclipsing Binary System" htt p://www.tufts.edu/as/wright_center/fellows/sci_olympiad/Spok_2000_C_Instrcs_&_Quests.pdf...

i am looking for the equation for angular diameter in relation to an objects distance and diameter. i need it expressed in arc seconds, not radians. anyone know it?

cool. thanks for your help dude

now they do.. just delete the space between the "h" and the "t" in http

This problem deals with two main sequence stars in an eclipsing binary star system. I need to determine the system's peiod and separation (P and a). Right now i know that the brightest star has an absolute magnitude of -1 (219 solar luminosity), is 17,000 degrees kelvin, has a radius of 1.74...

crap... i meant to say apparent magnitude of star Q. my bad

Eclipsing binary problem! I am really frustrated! I have been looking at this problem for a while and i am really getting frustrated. I asked my astronomy teacher, but we are both stumped. This isn't graded, but i really need to learn how to do it for science olympiad. Here it is. I have...

physics/astronomy eclipsing binary problem! help! I have been looking at this problem for a while and i am really getting frustrated. Here it is. I have an eclipsing binary system with a period of 1 year. Star Q has 800 solar luminosities, while the other star, star R, has 5 solar...
