Extreme Debris Disks: Insights into Violent Collisions in Planet Formation and Destruction
Kate Y. L. Su, Attila Moor, Agnes Kospal +7
Debris disks are dusty structures around mature stars, primarily identified by infrared excesses in the stellar spectra. A subset, known as extreme debris disks (EDDs), exhibits st…
A radially broad collisional cascade in the debris disk of Ophiuchi observed by JWST
Yinuo Han, Mark Wyatt, Kate Y. L. Su +13
The A1V star Oph, at a distance of 29.7 pc, is known from Spitzer imaging to host a debris disk with a large radial extent and from its spectral energy distribution to host in…
Resolving the terrestrial planet-forming region of HD 172555 with ALMA: I. Post-impact dust distribution
Zoe Roumeliotis, Luca MatrÃ, Grant M. Kennedy +5
Giant impacts between planetary embryos are a natural step in the terrestrial planet formation process and are expected to create disks of warm debris in the terrestrial regions of…
Discovery of Volatile Gas in the Giant Impact Disk around the 150-Myr old HD 23514
Kate Y. L. Su, Attila Moór, Chengyan Xie +8
We report the discovery of CO gas emission around HD 23514, an F5V star in the 150 Myr-old Pleiades cluster, hosting one of the rare giant-impact disks with unique minera…
