Interstellar medium and star formation studies with the Square Kilometre
  Array
  Stars and planetary systems are formed out of molecular clouds in the
interstellar medium. Although the sequence of steps involved in star formation
are generally known, a comprehensive theory which describes the details of the
processes that drive formation of stars is still missing. The Square Kilometre
Array (SKA), with its unprecedented sensitivity and angular resolution, will
play a major role in filling these gaps in our understanding. In this article,
we present a few science cases that the Indian star formation community is
interested in pursuing with SKA, which include investigation of AU-sized
structures in the neutral ISM, the origin of thermal and non-thermal radio jets
from protostars and the accretion history of protostars, and formation of
massive stars and their effect on the surrounding medium.
