Production of Ammonia Makes Venusian Clouds Habitable and Explains Observed Cloud-Level Chemical Anomalies
William Bains, Janusz J. Petkowski, Paul B. Rimmer +1
The atmosphere of Venus remains mysterious, with many outstanding chemical connundra. These include: the unexpected presence of ~10 ppm O2 in the cloud layers; an unknown compositi…
Venusian phosphine: a 'Wow!' signal in chemistry?
William Bains, Janusz J. Petkowski, Sara Seager +6
The potential detection of ppb levels phosphine (PH3) in the clouds of Venus through millimeter-wavelength astronomical observations is extremely surprising as PH3 is an unexpected…
Physical Characterization of Main-Belt Comet (248370) 2005 QN173
Henry H. Hsieh, Colin O. Chandler, Larry Denneau +17
We report results from new and archival observations of the newly discovered active asteroid (248370) 2005 QN_137, which has been determined to be a likely main-belt comet based on…
JexoSim 2.0: End-to-End JWST Simulator for Exoplanet Spectroscopy -- Implementation and Case Studies
Subhajit Sarkar, Nikku Madhusudhan
The recently developed JWST Exoplanet Observation Simulator (JexoSim) simulates transit spectroscopic observations of exoplanets by JWST with each of its four instruments using a t…
Low levels of sulphur dioxide contamination of Venusian phosphine spectra
Jane S. Greaves, Paul B. Rimmer, Anita M. S. Richards +7
New analysis is presented of the 1.1 mm wavelength absorption lines in Venus' atmosphere that suggested the presence of phosphine. We retrieve a sulphur dioxide observation from th…
The formation of planetary systems with SPICA
I. Kamp, M. Honda, H. Nomura +38
In this era of spatially resolved observations of planet forming disks with ALMA and large ground-based telescopes such as the VLT, Keck and Subaru, we still lack statistically rel…
Possibilities for an Aerial Biosphere in Temperate Sub Neptune-Sized Exoplanet Atmospheres
Sara Seager, Janusz J. Petkowski, Maximilian N. Günther +3
The search for signs of life through the detection of exoplanet atmosphere biosignature gases is gaining momentum. Yet, only a handful of rocky exoplanet atmospheres are suitable f…
The Atacama Cosmology Telescope: A search for Planet 9
Sigurd Naess, Simone Aiola, Nick Battaglia +37
We use Atacama Cosmology Telescope (ACT) observations at 98 GHz (2015--2019), 150 GHz (2013--2019) and 229 GHz (2017--2019) to perform a blind shift-and-stack search for Planet 9.…
ALMA imaging of the M-dwarf Fomalhaut C's debris disc
Patrick F. Cronin-Coltsmann, Grant M. Kennedy, Paul Kalas +9
Fomalhaut C (LP 876-10) is a low mass M4V star in the intriguing Fomalhaut triple system and, like Fomalhaut A, possesses a debris disc. It is one of very few nearby M-dwarfs known…
Recovery of Spectra of Phosphine in Venus' Clouds
Jane S. Greaves, Anita M. S. Richards, William Bains +7
We recover PH3 in the atmosphere of Venus in data taken with ALMA, using three different calibration methods. The whole-planet signal is recovered with 5.4σ confidence using Venus…
NEOExchange -- An online portal for NEO and Solar System science
T. A. Lister, E. Gomez, J. Chatelain +4
Las Cumbres Observatory (LCO) has deployed a network of ten identical 1-m telescopes to four locations. The global coverage and flexibility of the LCO network makes it ideal for di…
