Magnitude and distance modulus a) What is the absolute magnitude and distance modulus for each of the following stars: i)m=+5.0, d=200 pc ii) m=-3.5, d=7 pc iii) m=+6.8, p=0.003" (p is the parallax angle) b) The Sun has an apparent magnitude of -26.8. Calculate i)its absolute magnitude. ii) the apparent magnitude it would have at the distance of a Centauri (1.3 pc). iii) the apparent magnitude it would have if it were 2 kpc away.

Suppose that two identical stars (they have the same total light output) are located so that star A is at a distance of 5 pc and star B is at a distance of 25 pc from Earth. How will star B appear, compared with star A? A star is at such a distance that its apparent magnitude (m) is 10 magnitudes fainter than its absolute magnitude (M). How far away is it? Three stars have the following apparent (m) and...
Could one of the stars listed in the table above be an RR Lyrae star?
Cosmic DistancesDISTANCE MODULUS- For this lab, we will focus on two techniques that can be used to measure the distance modulus of objects in deep space - supernovas and Cepheid variable stars. Before we begin, though, we must understand what "distance modulus" means.- Read through the background material on distance modulus.- Use the distance modulus page to complete the following table:ObjectApparent Magnitude (m)Absolute Magnitude (M)Distance Modulus (m-M)Distance (pc)Star A2.410Star B516Star C1025Star D8.50.5- Could one of the stars listed in the...
