An unusual reservoir of water emission in the VV CrA A protoplanetary disk
Colette Salyk, Klaus M. Pontoppidan, Andrea Banzatti +7
We present an analysis of an unusual pattern of water vapor emission from the 2 Myr-old low-mass binary system VV CrA, as observed in infrared spectra obtained with VLT-CRIRE…
Near-infrared spectra of the inflated post-common envelope brown dwarf NLTT 5306B
Cam Buzard, Sarah Casewell, Joshua Lothringer +1
NLTT 5306 is a post-common envelope binary made up of a white dwarf host and brown dwarf companion that has shown evidence of inflation and active mass donation despite not filling…
The TW Hya Rosetta Stone Project II: Spatially resolved emission of formaldehyde hints at low-temperature gas-phase formation
Jeroen Terwisscha van Scheltinga, Michiel R. Hogerheijde, L. Ilsedore Cleeves +15
Formaldehyde (HCO) is an important precursor to organics like methanol (CHOH). It is important to understand the conditions that produce HCO and prebiotic molecules dur…
The Evolution of Disk Winds from a Combined Study of Optical and Infrared Forbidden Lines
I. Pascucci, A. Banzatti, U. Gorti +18
We analyze high-resolution (dv=<10km/s) optical and infrared spectra covering the [OI] 6300 angstrom and [NeII] 12.81 micron lines from a sample of 31 disks in different evolutiona…
An unbiased ALMA spectral survey of the LkCa 15 and MWC 480 protoplanetary disks
Ryan A. Loomis, Karin I. Öberg, Sean M. Andrews +13
The volatile contents of protoplanetary disks both set the potential for planetary chemistry and provide valuable probes of defining disk system characteristics such as stellar mas…
An evolutionary study of volatile chemistry in protoplanetary disks
Jennifer B. Bergner, Karin I. Oberg, Edwin A. Bergin +11
The volatile composition of a planet is determined by the inventory of gas and ice in the parent disk. The volatile chemistry in the disk is expected to evolve over time, though th…
