Sudden extreme obscuration of a Sun-like main-sequence star: evolution of the circumstellar dust around ASASSN-21qj
Jonathan P. Marshall, Steve Ertel, Francisca Kemper +6
ASASSN-21qj is a distant Sun-like star that recently began an episode of deep dimming events after no prior recorded variability. Here we examine archival and newly obtained optica…
How much large dust could be present in hot exozodiacal dust systems?
T. A. Stuber, F. Kirchschlager, T. D. Pearce +3
An infrared excess over the stellar photospheric emission of main-sequence stars has been found in interferometric surveys, commonly attributed to the presence of hot exozodiacal d…
Long-term Evolution of Warps in Debris Disks -- Application to the Gyr-old system HD 202628
Madison Brady, Virginie Faramaz-Gorka, Geoffrey Bryden +1
We present the results of N-body simulations meant to reproduce the long-term effects of mutually inclined exoplanets on debris disks, using the HD 202628 system as a proxy. HD 202…
Second-generation protoplanetary discs around evolved binaries: a high-resolution polarimetric view with SPHERE/IRDIS
Kateryna Andrych, Devika Kamath, Jacques Kluska +3
Binary post-asymptotic giant branch (post-AGB) stars are products of a poorly understood binary interaction process that occurs during the AGB phase. These systems comprise of a po…
Measuring the variability of directly imaged exoplanets using vector Apodizing Phase Plates combined with ground-based differential spectrophotometry
Ben J. Sutlieff, Jayne L. Birkby, Jordan M. Stone +11
Clouds and other features in exoplanet and brown dwarf atmospheres cause variations in brightness as they rotate in and out of view. Ground-based instruments reach the high contras…
The SHARDDS survey: limits on planet occurrence rates based on point sources analysis via the Auto-RSM framework
C. -H. Dahlqvist, J. Milli, O. Absil +7
In the past decade, HCI surveys provided new insights about the frequency and properties of substellar companions at separation larger than 5 au. In this context, our study aims to…
