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…
Asymmetrical tidal tails of open star clusters: stars crossing their cluster's prah challenge Newtonian gravitation
Pavel Kroupa, Tereza Jerabkova, Ingo Thies +14
After their birth a significant fraction of all stars pass through the tidal threshold (prah) of their cluster of origin into the classical tidal tails. The asymmetry between the n…
A detailed study of the barium central star of the planetary nebula Abell 70
David Jones, Henri M. J. Boffin, Alex J. Brown +4
We present a detailed study of the barium star at the heart of the planetary nebula Abell 70. Time-series photometry obtained over a period of more than ten years demonstrates that…
The Present and Future of Astronomy (ASTRO2022)
Giacomo Beccari, Henri M. J. Boffin, Paola Andreani +7
Being one of the most fascinating and ancient sciences, astronomy has always played a special role in society. In 2022 ESO organised an online conference to offer the community a p…
A tale of caution: the tails of NGC 752 are much longer than claimed
Henri M. J. Boffin, Tereza Jerabkova, Giacomo Beccari +1
Understanding the exact extent and content of tidal tails of open clusters provide useful clues on how field stars populate the Milky Way. We reanalyse, using Gaia EDR3 data, the t…
TOI-2046b, TOI-1181b and TOI-1516b, three new hot Jupiters from \textit{TESS}: planets orbiting a young star, a subgiant and a normal star
Petr Kabáth, Priyanka Chaturvedi, Phillip J. MacQueen +54
We present the confirmation and characterization of three hot Jupiters, TOI-1181b, TOI-1516b, and TOI-2046b, discovered by the TESS space mission. The reported hot Jupiters have or…
