Direct spectroscopic confirmation of the young embedded proto-planet WISPIT 2c
Chloe Lawlor, Richelle F. van Capelleveen, Guillaume Bourdarot +18
WISPIT 2 is a nearby young star with a multi-ringed disk which was recently confirmed to host a ~4.9 MJup gas giant planet embedded in a large (60 au) gap at a radial separation of…
Multi-wavelength ALMA Imaging of HD 34282: Dust-trapping Signatures of a Vortex Candidate
Xiaoyi Ma, Fangyuan Yu, Ruobing Dong +8
Azimuthal arcs in millimeter continuum emission from protoplanetary disks are often attributed to dust-trapping vortices, but definitive observational confirmation of vortices rema…
Non-detection of J1407b in ALMA Band 7 Observations
Pamela Klaassen, Matthew Kenworthy, Eric Mamajek +4
We report on ALMA Band 7 continuum observations towards the star 1SWASP J140747.93-394542.6 taken in mid 2024. These observations were a follow-up of a previous detection of an emi…
ALMA High-resolution Observation for the Transitional Disk around IRAS 04125+2902
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…
WIde Separation Planets In Time (WISPIT): A Gap-clearing Planet in a Multi-ringed Disk around the Young Solar-type Star WISPIT 2
Richelle F. van Capelleveen, Christian Ginski, Matthew A. Kenworthy +17
In the past decades several thousand exoplanet systems have been discovered around evolved, main-sequence stars, revealing a wide diversity in their architectures. To understand ho…
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…
