ASASSN-21js: A multi-year transit of a ringed disc
T. H. Pramono, M. A. Kenworthy, R. van Boekel
The early-type star ASASSN-21js started to fade in 2021, as was detected by the All Sky Automated Survey for Supernovae, undergoing a multi-year eclipse that is still underway. We…
High contrast at short separation with VLTI/GRAVITY: Bringing Gaia companions to light
N. Pourré, T. O. Winterhalder, J. -B. Le Bouquin +173
Since 2019, GRAVITY has provided direct observations of giant planets and brown dwarfs at separations of down to 95 mas from the host star. Some of these observations have provided…
Direct detectability of tidally heated exomoons by photometric orbital modulation
E. Kleisioti, D. Dirkx, X. Tan +1
(Aims) We investigate whether volcanic exomoons can be detected in thermal wavelength light curves due to their phase variability along their orbit. The method we use is based on t…
The formation of transiting circumplanetary debris discs from the disruption of satellite systems during planet-planet scattering
Alexander J. Mustill, Melvyn B. Davies, Matthew A. Kenworthy
Several stars show deep transits consistent with discs of roughly 1 Solar radius seen at moderate inclinations, likely surrounding planets on eccentric orbits. We show that this co…
BeyonCE -- Light Curve Modelling Beyond Circular Eclipsers I. Shallot Explorer
Dirk van Dam, Matthew Kenworthy
Context. Time-series photometry has given astronomers the tools to study time-dependent astrophysical phenomena, from stellar activity to fast radio bursts and exoplanet transits.…
Polarimetric differential imaging with VLT/NACO. A comprehensive PDI pipeline for NACO data (PIPPIN)
S. de Regt, C. Ginski, M. A. Kenworthy +9
The observed diversity of exoplanets can possibly be traced back to the planet formation processes. Planet-disk interactions induce sub-structures in the circumstellar disk that ca…
