"Unveiling the Mysteries of Planet Formation Around Young Stars"

A groundbreaking survey using ESO's VLT has provided new insights into planet formation by capturing images of over 80 young stars with potential planet-forming disks. The research, presented in three papers, reveals the diversity of planet-forming disks and their intricate features, such as spiral arms and large cavities carved out by forming planets. The observations, gathered from three different star-forming regions, offer valuable data for understanding the processes that lead to planet formation and could inspire future scientific exploration.

Metal-Scarred Cannibal Star: A Celestial Phenomenon Unprecedented in Astronomy

Astronomers using ESO's VLT have discovered a scar on the surface of a white dwarf star, WD 0816-310, caused by ingesting planetary debris, indicating the role of the star's magnetic field in this process. The scar is a concentration of metals from a planetary fragment, possibly as large as Vesta, and is located on one of the star's magnetic poles. This unique discovery sheds light on the dynamics of planetary systems even after the death of a star and provides insights into the bulk composition of exoplanets.
