A persistent bow shock in a diskless magnetised accreting white dwarf
Krystian Ilkiewicz, Simone Scaringi, Domitilla de Martino +9
Stellar bow shocks are formed when an outflow interacts with the interstellar medium. In white dwarfs accreting from a binary companion, outflows are associated with either strong…

Limits on the atmospheric metallicity and aerosols of the sub-Neptune GJ 3090 b from high-resolution CRIRES+ spectroscopy
Luke T. Parker, João M. Mendonça, Hannah Diamond-Lowe +9
The sub-Neptune planets have no solar system analogues, and their low bulk densities suggest thick atmospheres containing degenerate quantities of volatiles and H/He, surrounding c…
