Some white dwarfs show heavy elements in their spectra — evidence of “pollution” from disrupted asteroids or planets. This helps us study the chemical makeup of exoplanetary systems.
Subrahmanyan Chandrasekhar discovered that a white dwarf cannot exceed about 1.4 solar masses. If it gains more mass (e.g., from a companion star), it may:
Before diving into where to find the PDFs, let’s understand the subject. A white dwarf is the final evolutionary state of stars whose mass is not high enough to become a neutron star or black hole. Our own Sun will become a white dwarf in about 5 billion years. white dwarf pdf vk
