What celestial body results if mass falls below the critical fusion threshold of $0.08 M_{\odot}$?
Answer
Brown dwarfs
A body must possess mass greater than approximately $0.08$ times the mass of the Sun to sustain stable hydrogen fusion; anything below this range falls into the category of brown dwarfs.
