White dwarf

In News 
  • As per the recent study, a bright explosion born out of the cosmic dance of a white dwarf and its companion star resulting in thick dust around an imploding novae could unravel mysteries behind the start of life.
Novae 
  • A nova is an astronomical event in which a strong explosion occurs temporarily, thus increasing the brightness and then slowly darkening over weeks or months.
  • It generally occurs in a binary system (two stars orbiting around a common centre of mass) consisting of a white dwarf and a main sequence star.
  • Space dust out of collisions may have propelled organisms over enormous distances between planets to start life on a planet.
  •  It has been observed only in a few novae within 30 to 100 days after an outburst, as compared to interstellar dust, which typically takes a few thousand years to form and hence provided opportunity to study the dust formation process in novae.
