1.	1.a) what determine aster’s luminosity?Belowb)consider two stars with the statistics belowName Temperature Apparent magnitude Absolute magnitude Antares A 2650k +0.92 -4.5 Ross 128 2650k +11.1 +13.5a) I)which of these stars looks brighter in the sky? Support your choice?ii)which of these stars is the most luminosity? Justify your answer without calculations.Iii)one of these stars is closer to us than 10parsecs, one is farther away. Which is which? Justify your answer with words instead of calculations.
Answer» Answer: A STAR's luminosity can be determined from two stellar characteristics: size and effective temperature. ... An alternative WAY to MEASURE stellar luminosity is to measure the star's apparent brightness and DISTANCE.
