Detection of Solar-like Oscillations and Granulation at Infrared Wavelengths using JWST
Angharad Weeks, Daniel Huber, Timothy R. Bedding +8
Stellar oscillations and granulation are key probes of stellar convection, one of the most poorly understood processes in stars. Stellar models predict strong wavelength dependence…
A Highly Reflective Atmosphere on the Lava World TOI-561b Revealed by JWST/NIRSpec Phase Curve
Samuel Boucher, Lisa Dang, Alex McGinty +15
Ultra-short period (USP) rocky planets are expected to be depleted of any substantial gaseous envelope due to the intense irradiation they receive from their host star, making the…
Homogeneous stellar parameters for 717,807 TESS FGK stars using Gaia DR3
Francesca Waines, Angharad Weeks, Vincent Van Eylen
Precise homogeneous stellar characterisation is crucial for our understanding of the physical properties of exoplanets, their demographics and the environment from which they are f…
Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager
Vincent Van Eylen, Richard Massey, Saeeda Awan +167
Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…
A link between rocky exoplanet composition and stellar age
Angharad Weeks, Vincent Van Eylen, Daniel Huber +7
Interior compositions are key for our understanding of Earth-like exoplanets. The composition of the core can influence the presence of a magnetic dynamo and the strength of gravit…
TOI-544 b: a potential water-world inside the radius valley in a two-planet system
H. L. M. Osborne, V. Van Eylen, E. Goffo +32
We report on the precise radial velocity follow-up of TOI-544 (HD 290498), a bright K star (V=10.8), which hosts a small transiting planet recently discovered by the Transiting Exo…
