A major goal of the Habitable Worlds Observatory (HWO) is to precisely characterize exoplanets and their atmospheres.
Astrometric monitoring of stars provides a promising method for discovery of low-mass planets around nearby Sun-like stars.
The outer regions of AGN disks have temperatures similar to those of circumstellar disks, permitting dust condensation. Therefore, planet formation and growth could be active in these dust tori through […]
The crystallinity of water ice not only records the thermal history experienced by an astronomical body, but also affects the composition of forming planets by controlling the trapping of volatile […]
Suppose there are signs of extraterrestrial life and we have not yet been able to detect them. What does that mean?
This paper aims to review the diverse range of technosignatures that have been proposed in the literature.
We report the discovery and characterisation of the multi-planetary system around TOI-4311, a K dwarf kinematically between the Galactic thick disk and Hercules stream. TOI-4311 hosts an ultra-short-period super-Earth (P∼0.99 […]
Detecting light reflected off the dayside of an exoplanet in high-resolution spectroscopic data has proved to be a notoriously difficult endeavour. Despite several attempts, the faint signal has yet to […]
The Hertzsprung-Russell diagram (HRD) is central to stellar astrophysics but has rarely been used to interpret planet formation.
A planet that is about the size of Saturn, but with a temperature more like Earth’s, has an atmosphere rich in methane, according to a new study using NASA’s James […]
