Ground-based detection of an extended helium atmosphere in the Saturn-mass exoplanet WASP-69b
Henning, Thomas; Dreizler, Stefan; Sánchez-López, Alejandro +25 more
Hot gas giant exoplanets can lose part of their atmosphere due to strong stellar irradiation, and these losses can affect their physical and chemical evolution. Studies of atmospheric escape from exoplanets have mostly relied on space-based observations of the hydrogen Lyman-α line in the far ultraviolet region, which is strongly affected by inter…
A dust-enshrouded tidal disruption event with a resolved radio jet in a galaxy merger
Bondi, M.; Lundqvist, P.; Clements, D. L. +33 more
Tidal disruption events (TDEs) are transient flares produced when a star is ripped apart by the gravitational field of a supermassive black hole (SMBH). We have observed a transient source in the western nucleus of the merging galaxy pair Arp 299 that radiated >1.5 × 1052 erg at infrared and radio wavelengths but was not luminous at …
