Phosphine in the Venusian Atmosphere: A Strict Upper Limit from SOFIA GREAT Observations
M. A. Cordiner, G. L. Villanueva, H. Wiesemeyer +13
The presence of phosphine (PH) in the atmosphere of Venus was reported by Greaves et al. (2021a), based on observations of the J=1-0 transition at 267 GHz using ground-based, m…
NaCl & KCl in Io's Atmosphere
Erin Redwing, Imke de Pater, Statia Luszcz-Cook +3
We present the first comprehensive study of NaCl and KCl gases in Io's atmosphere in order to investigate their characteristics, and to infer properties of Io's volcanoes and subsu…
Pluto's atmosphere observations with ALMA: spatially-resolved maps of CO and HCN emission and first detection of HNC
E. Lellouch, B. Butler, R. Moreno +6
Following the detection of CO and HCN in Pluto's atmosphere, we report on new ALMA observations of Pluto with two main goals: (i) obtaining spatially-resolved measurements (~0.06''…
Ganymede's Surface Properties from Millimeter and Infrared Thermal Emission
Katherine de Kleer, Bryan Butler, Imke de Pater +4
We present thermal observations of Ganymede from the Atacama Large Millimeter Array (ALMA) in 2016-2019 at a spatial resolution of 300-900 km (0.1-0.2'' angular resolution) and fre…
No evidence of phosphine in the atmosphere of Venus by independent analyses
Geronimo Villanueva, Martin Cordiner, Patrick Irwin +24
The detection of phosphine (PH3) in the atmosphere of Venus has been recently reported based on millimeter-wave radio observations (Greaves et al. 2020), and its re-analyses (Greav…
ALMA Observations of Io Going into and Coming out of Eclipse
Imke de Pater, Statia Luszcz-Cook, Patricio Rojo +3
We present 1-mm observations constructed from ALMA [Atacama Large (sub)Millimeter Array] data of SO, SO and KCl when Io went from sunlight into eclipse (20 March 2018), and vic…
An attempt to detect transient changes in Io's SO2 and NaCl atmosphere
L. Roth, J. Boissier, A. Moullet +15
Io's atmosphere is predominately SO2 sustained by a combination of volcanic outgassing and sublimation. The loss from the atmosphere is the main mass source for Jupiter's large mag…
Disk-Integrated Thermal Properties of Ceres Measured at Millimeter Wavelengths
Jian-Yang Li, Arielle Moullet, Timothy N. Titus +2
