The fate of Earth during the Sun's giant phases: New constraints from ab initio tidal modelling and AGB mass loss
M. Esseldeurs, S. Mathis, L. Decin
The long-term evolution of planetary systems around solar-type stars is governed by the interplay between stellar expansion, tidal interactions, and mass loss during the red giant…
Information content of JWST transmission spectroscopy of the exoplanet HAT-P-12b from the optical to the mid-infrared
L. Heinke, M. Min, J. Bouwman +18
The James Webb Space Telescope (JWST) provides low- to medium-resolution spectra with unprecedented precision and broad near- to mid-infrared wavelength coverage, enabling detailed…
Competition between gravity waves excited by convection and tides in stars that host a companion
M. Esseldeurs, J. Ahuir, L. Amard +2
Asteroseismology has become a powerful tool in stellar astrophysics, offering unprecedented insights into the internal structures and dynamics of stars. It enables precise characte…
MICONIC: JWST/MIRI-MRS reveals heavily reprocessed PAH emission in the circum-nuclear disc of Centaurus A
L. Pantoni, M. Baes, L. Decin +23
Polycyclic aromatic hydrocarbons (PAHs) are key dust components in galaxies and play a fundamental role in the physics of the interstellar medium (ISM), yet their response to AGN 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.…
Interferometric view into RT Pav's long secondary period. binary vs oscillatory convective modes
B. Courtney-Barrer, X. Haubois, P. Wood +6
Long secondary periods (LSPs) occur in about one-third of evolved stars, yet their origin remains unclear. The leading explanations are oscillatory convective modes and a binary co…
