Evidence for the disruption of a planetary system during the formation of the Helix Nebula
Jonathan P. Marshall, Steve Ertel, Eric Birtcil +5
The persistence of planetary systems after their host stars evolve into their post-main sequence phase is poorly constrained by observations. Many young white dwarf systems exhibit…
Hot exozodis: cometary supply without trapping is unlikely to be the mechanism
Tim D. Pearce, Florian Kirchschlager, Gaël Rouillé +6
Excess near-infrared emission is detected around one fifth of main-sequence stars, but its nature is a mystery. These excesses are interpreted as thermal emission from populations…
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…
L-band nulling interferometry at the VLTI with Asgard/Hi-5: status and plans
Denis Defrère, Azzurra Bigioli, Colin Dandumont +34
Hi-5 is the L'-band (3.5-4.0 m) high-contrast imager of Asgard, an instrument suite in preparation for the visitor focus of the VLTI. The system is optimized for high-contrast a…
L-band Integral Field Spectroscopy of the HR 8799 Planetary System
David S. Doelman, Jordan M. Stone, Zackery W. Briesemeister +12
Understanding the physical processes sculpting the appearance of young gas-giant planets is complicated by degeneracies confounding effective temperature, surface gravity, cloudine…
