The Sonora Substellar Atmosphere Models VI. Red Diamondback: Extending Diamondback with SPHINX for Brown Dwarf Early Evolution
C. Evan Davis, Jonathan J. Fortney, Aishwarya Iyer +5
We extend the Sonora Diamondback brown dwarf evolution models to higher effective temperatures to treat the evolution of younger, higher mass objects. Due to an upper temperature l…
The SPHINX M-dwarf Spectral Grid. I. Benchmarking New Model Atmospheres to Derive Fundamental M-Dwarf Properties
Aishwarya R. Iyer, Michael R. Line, Philip S. Muirhead +2
About 70-80% of stars in our solar and galactic neighborhood are M dwarfs. They span a range of low masses and temperatures relative to solar-type stars, facilitating molecule form…
The Effect of Stellar Contamination on Low-resolution Transmission Spectroscopy: Needs Identified by NASA's Exoplanet Exploration Program Study Analysis Group 21
Benjamin V. Rackham, Néstor Espinoza, Svetlana V. Berdyugina +58
Study Analysis Group 21 (SAG21) of NASA's Exoplanet Exploration Program Analysis Group (ExoPAG) was organized to study the effect of stellar contamination on space-based transmissi…
EXOPLINES: Molecular Absorption Cross-Section Database for Brown Dwarf and Giant Exoplanet Atmospheres
Ehsan Gharib-Nezhad, Aishwarya R. Iyer, Michael R. Line +3
Stellar, substellar, and planetary atmosphere models are all highly sensitive to the input opacities. Generational differences between various state-of-the-art stellar/planetary mo…
The Influence of Stellar Contamination on the Interpretation of Near Infrared Transmission Spectra of Sub-Neptune Worlds around M-Dwarfs
Aishwarya R. Iyer, Michael R. Line
The impact of unocculted stellar surface heterogeneities in the form of cool spots and hot faculae on the spectrum of a transiting planet has been a daunting problem for the charac…
Forecasting the Impact of Stellar Activity on Transiting Exoplanet Spectra
Robert T. Zellem, Mark R. Swain, Gael Roudier +8
Exoplanet host star activity, in the form of unocculted star spots or faculae, alters the observed transmission and emission spectra of the exoplanet. This effect can be exacerbate…
Quantifying the Impact of Spectral Coverage on the Retrieval of Molecular Abundances from Exoplanet Transmission Spectra
John W. Chapman, Robert T. Zellem, Michael R. Line +14
Using forward models for representative exoplanet atmospheres and a radiometric instrument model, we have generated synthetic observational data to explore how well the major C- an…
A Characteristic Transmission Spectrum dominated by HO applies to the majority of HST/WFC3 exoplanet observations
Aishwarya R. Iyer, Mark R. Swain, Robert T. Zellem +4
Currently, 19 transiting exoplanets have published transmission spectra obtained with the Hubble/WFC3 G141 near-IR grism. Using this sample, we have undertaken a uniform analysis i…
