Question

9) How distant is a star whose modulus is -7.5? 10) If its apparent magnitude (m) = +13.5 and absolute magnitude (M) = +10, w

Answer 1

Answer #1

Dear Student,

All solutions are based on 2 formulas

$m-M=5\log d-5$

m= Apparent magnitude, M= Absolute magnitude, d= Distance of star in parsecs(pc)

&

d= 1/p where p= parallax in arc seconds,

d= distance of star in parsecs(pc)

Please follow the calculation as follows...

Happy to help you...

Hi! So this table on the picture has star information needed. the queastion is: “A star whose apparent magnitude and absolute magnitude are identical is licated at 10 persecs away from us (by definition). Star C is at 10 pc. Of the other four stars, rank them from closest, closer, farther, farthest. (HINT: figure out if a star would be brighter or dimmer IF it were located at 10 persecs.)” So on second picture were my answers, and i got...
