Heavier stars, however, burn through their fuel, and the subsequent byproducts, much faster than low mass stars. The energy made by the fusion of heavier and heavier elements balanced the star against the force of gravity. These reactions continued until they formed iron in the core of the star.
Star formation. Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as "stellar nurseries" or " star -forming regions", collapse and form stars. [1] As a branch of astronomy, star formation includes the study of the interstellar medium (ISM) and giant molecular clouds (GMC ...
Star Formation: Low-Mass: Low-mass stars like our Sun are formed in dense cores of molecular gas clouds. At optical wavelengths, the star formation process is hidden from view by interstellar dust, and even at infrared wavelengths the most deeply embedded protostars often remain unseen. Since most of the material in dense cores is cold, below ...
Sep 16, 2020 · A visualization flying into the nebula Gum 29 and the star cluster Westerlund 2 at its core. All stars are born in clouds of dust and gas like the Pillars of Creation in the Eagle Nebula pictured below. In these stellar nurseries, clumps of gas form, pulling in more and more mass as time passes. As they grow, these clumps start to spin and heat up.
Low-mass stars like our Sun are formed in the dense cores of large molecular gas clouds. The star formation process is hidden from view at optical wavelengths due to the large amounts of gas and dust surrounding the forming star, and even at infrared wavelengths the most deeply embedded protostars are often difficult to study.
White dwarfs are formed from the collapse of low mass stars, less than about 10 time the mass of the Sun, in which the star loses most of its mass in a wind, leaving behind a core that is less than 1.44 solar mass, whereas neutron stars are formed in the catastrophic collapse of the core of a massive star.

The dynamics of collapsing cores and star formation. Abstract Low-mass stars are generally understood to form by the gravitational collapse of the dense molecular clouds known as starless cores. Continuum observations have not been able to distinguish among the several different hypotheses that describe the collapse because their predicted ...
