Exocast-46 d: Exoplanet News from May & June 2020
This month Hannah, Hugh, and Andrew go through the slew of exoplanet papers from discoveries, characterisation, and astrobiology including the following:
Discoveries:
- Buzzword alert! A mini-Neptune and Venus-zone planet in the radius valley orbiting an M2 star has been validated with the Habitable-zone planet finder.
- Four jovian sized worlds discovered around the low luminosity stars
- Wendelstein-1b and 2b
- A habitable-zone planet in Kepler-160?
- The finally published discovery of AU Mic b
- Discovery of Gliese 887b & c
Characterisation:
- Ultra-hot Jupiter WASP-121b got two papers this month. One looking for Cr and V, and the other cataloging an array of metals in its atmosphere.
- Hubble WFC3 IR grism spectroscopy of the warm Neptune HD 106315c
- Another search for TiO in the atmosphere of WASP-33b.
- Hubble PanCET program has a new transmission spectrum out of HAT-P-32b
- TESS phasecurve observations of the brown dwarf KELT-1b
- The most likely clouds muting and obscuring molecular features in transmission spectra are composed of magnesium silicates.
- 3D GCM models to map the formation of hydrocarbon haze in the atmosphere of WASP-43b
Astrobiology:
- Mineral dust increases the habitability of terrestrial planets but confounds biomarker detection
- The Effect Of Varying Atmospheric Pressure Upon Habitability And Biosignatures Of Earth-like Planets
- Reports from the Goldschmidt conference
- and… The strangely precise conclusion that there are 36 intelligent civilisations in out galaxy.
