Ayumu Shoshi, Takayuki Muto, Quincy Bosschaart +5
Recently, the youngest transiting planet was discovered around the T Tauri star, IRAS 04125+2902, in the Taurus-Auriga star-forming region. This system is crucial for understanding…
ALMA reveals thermal and non-thermal desorption of methanol ice in the HD 100546 protoplanetary disk
Lucy Evans, Alice S. Booth, Catherine Walsh +8
Methanol (CHOH) and formaldehyde (HCO) are chemically coupled organic molecules proposed to act as an intermediate step between simple molecules and more complex prebiotic…
The rapid formation of macromolecules in irradiated ice of protoplanetary disk dust traps
Niels F. W. Ligterink, Paola Pinilla, Nienke van der Marel +4
Organic macromolecular matter is the dominant carrier of volatile elements such as carbon, nitrogen, and noble gases in chondrites -- the rocky building blocks from which Earth for…
Measuring the and isotopic ratios of volatile sulfur during planet formation
Alice S. Booth, Maria N. Drozdovskaya, Milou Temmink +9
Stable isotopic ratios constitute powerful tools for unraveling the thermal and irradiation history of volatiles. In particular, we can use our knowledge of the isotopic fractionat…
Rocky planet formation in compact disks around M dwarfs
M. Sanchez, N. van der Marel, M. Lambrechts +2
Rocky planets in compact configurations are the most common ones around M dwarfs. Many disks around very low mass stars (between 0.1 and 0.5 M) are rather compact and small…
