Complete Question:

The five stars or star like objects are given below:

1) Newly formed star

2) Protostar

3) white dwarf; single star(not binary)

4) 1 main sequence star,; single star(not binary)

5) 1.4 white dwarf; binary with a red giant companion

Check below for the explanations

Explanation:

The lifetime of the star will be given by:

Lifetime of the sun,

1) For the newly formed   star

The star is in the main sequence

2) Protostar

The star is a brown dwarf, it cannot fuse hydrogen at its core

3)   white dwarf; single star(not binary)

At this time, a lot of its initial radiation has been emitted and the temperature has become low. It is a cold white dwarf

4) 1 main sequence star,; single star(not binary)

At this time, a lot of radiation will be emitted, the star is a hot white dwarf

5)  1.4 white dwarf; binary with a red giant companion

At this time, it will continue to undergo a gravitational collapse from the nearest future, so It is a neutron star.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
