Spirals and Vertical Motions in the Planet-Forming Disk around HD 100546. A multi-line study of its gas kinematics
Lisa Wölfer, Andrés F. Izquierdo, Alice Booth +5
HD100546 represents a particularly interesting target to study dynamical planet-disk interactions as various features have been observed in both the dust and gas that provide direc…
Chemical signatures of a warped protoplanetary disc
Alison K. Young, Richard Alexander, Catherine Walsh +3
Circumstellar discs may become warped or broken into distinct planes if there is a stellar or planetary companion with an orbit that is misaligned with respect to the disc. There i…
Dust continuum emission and the upper limit fluxes of sub-millimeter water lines of the protoplanetary disk around HD 163296 observed by ALMA
Shota Notsu, Eiji Akiyama, Alice Booth +6
In this paper, we analyse the upper limit fluxes of sub-millimeter ortho-HO 321 GHz, para-HO 322 GHz, and HDO 335 GHz lines from the protoplanetary disk a…
Sulphur monoxide exposes a potential molecular disk wind from the planet-hosting disk around HD100546
Alice Booth, Catherine Walsh, Mihkel Kama +3
Sulphur-bearing volatiles are observed to be significantly depleted in interstellar and circumstellar regions. This missing sulphur is postulated to be mostly locked up in refracto…
The Impact of External Radiation on the Inner Disk Chemistry of Planet Formation
Jenny K. Calahan, Karin Ãberg, Alice Booth
The vast majority of young stars hosting planet-forming disks exist within clustered environments, like the Orion Nebula, implying that seemingly `extreme' UV environments (10^4 G_…
Molecules with ALMA at Planet-forming Scales (MAPS) VIII: CO Gap in AS 209--Gas Depletion or Chemical Processing?
Felipe Alarcón, Arthur Bosman, Edwin Bergin +22
Emission substructures in gas and dust are common in protoplanetary disks. Such substructures can be linked to planet formation or planets themselves. We explore the observed gas s…
The GTC exoplanet transit spectroscopy survey VIII. Flat transmission spectrum for the warm gas giant WASP-80
Hannu Parviainen, Enric Palle, Guo Chen +7
We set out to study the atmosphere of WASP-80b, a warm inflated gas giant with an equilibrium temperature of 800~K, using ground-based transmission spectroscopy covering the…
Complex Organics Surrounding the FU Ori-Type Object V1057 Cyg Indicative of Sublimated Ices
Jenny K. Calahan, Edwin A. Bergin, Merel van't Hoff +5
FU Ori and EX Lup type objects present natural experiments for understanding a critical stage in the star and planet formation process. These objects offer insight into the diversi…
