A stellar collision scenario may explain why planet-forming disks in the Orion Nebula appear younger than their host stars. Intense radiation from the central massive star strips material from these disks, sculpting them into tadpole-like shapes.
Four giant planets have been discovered using high-cadence microlensing surveys. The planets orbit stars with masses between 7% and 60% of the Sun's mass. All the planets appear to lie beyond the snow lines of their hosts.
Announced in 2007, CT Chamaeleontis b is an enormous gas giant exoplanet with a mass of 17 Jupiters orbiting a K-type star. It provides unique insights into planetary formation limits.
JWST has tracked shifting water-ice clouds and dynamic gases in the atmosphere of the coldest known brown dwarf. The study reveals surprising meteorological links between failed stars and giant planets.
Astronomers are utilizing the Webb and Spitzer space telescopes to analyze violent planetesimal collisions and debris disks around distant stars, revealing how planetary systems evolve.
