Astronomers have unveiled an intriguing secret behind the dusty veil of a young star named T Chamaeleontis, quietly forming planets about 350 light-years from Earth when part of its circumstellar inner wall collapsed partially. This can help rewrite our understanding of how planetary systems evolve.
T Chamaeleontisan (T. Cha) is an extraordinary star is no ordinary young star. It is surrounded by a planet-forming disk called circumstellar disk that contains a wide gap—likely carved out by a newborn planet. Normally, the dense inner regions of such disks act like a protective wall or veil blocking much of the star’s ultraviolet light from reaching the colder, outer regions. That shielding makes Poly Atomic Hrydrocarbons (PAHs), flat, honeycomb-shaped molecules (Benzene rings) made of carbon and hydrogen thought to be among the earliest precursors of life’s chemistry, especially hard to detect around low-mass, Sun-like stars.
