29. Luminosity can be related to the brightness of a star or any other astronomical object. Luminosity is the total amount of energy emitted by an object per unit time. Brightness is actually the luminosity of an object in a particular spectral region.
Size and effective temperature of stars determines its luminosity.
30. Alpha Centauri A is a main sequence star of spectral class K1V.
37. The SuperGiants occupy a position above the main sequence stars in the H-R Diagram. They have luminosity of the range 104 to 106 Lsun and temperature range of 20000 to 2500 Kelvins. They are the brightest stars in the HR Diagram.
38. H-R stands for Hertzsprung- Russel Diagram.
39. Cecilia Payne Gaposchkin first discovered the stars which are made up of hydrogen and helium
40. Stars are born in Nebulas which are huge, cold dust and gas clouds. These are basically molecular clouds of interstellar dust and gas matters.
41. Stars are formed when elements are subjected to tremendous pressure and eventually, they undergo fusion to form stars. Fusion is initiated by the compression of elements by the gravitational forces.
