Identifying Planetary Biosignature Impostors: Spectral Features of CO and O4 Resulting from Abiotic O2/O3 Production
Edward W. Schwieterman, Victoria S. Meadows, Shawn D. Domagal-Goldman +6
O2 and O3 have been long considered the most robust individual biosignature gases in a planetary atmosphere, yet multiple mechanisms that may produce them in the absence of life ha…
3D modeling of GJ1214b's atmosphere: formation of inhomogeneous high clouds and observational implications
Benjamin Charnay, Victoria Meadows, Amit Misra +2
The warm sub-Neptune GJ1214b has a featureless transit spectrum which may be due to the presence of high and thick clouds or haze. Here, we simulate the atmosphere of GJ1214b with…
Detecting and Constraining N Abundances in Planetary Atmospheres Using Collisional Pairs
Edward W. Schwieterman, Tyler D. Robinson, Victoria S. Meadows +2
Characterizing the bulk atmosphere of a terrestrial planet is important for determining surface pressure and potential habitability. Molecular nitrogen (N) constitutes the larg…
Transient Sulfate Aerosols as a Signature of Exoplanet Volcanism
Amit Misra, Joshua Krissansen-Totton, Matthew C. Koehler +1
Geological activity is thought to be important for the origin of life and for maintaining planetary habitability. We show that transient sulfate aerosols could be a signature of ex…
Discriminating Between Cloudy, Hazy and Clearsky Exoplanets Using Refraction
Amit Misra, Victoria Meadows
We propose a method to distinguish between cloudy, hazy and clearsky (free of clouds and hazes) exoplanet atmospheres that could be applicable to upcoming large aperture space and…
The Effects of Refraction on Transit Transmission Spectroscopy: Application to Earth-like Exoplanets
Amit Misra, Victoria Meadows, Dave Crisp
We quantify the effects of refraction in transit transmission spectroscopy on spectral absorption features and on temporal variations that could be used to obtain altitude-dependen…
