Where does the simplified Stellar Contamination Model fail in Exoplanet Transmission Spectroscopy?
Viktor Y. D. Sumida, Raissa Estrela, Mark Swain +1
Stellar photospheric heterogeneities (e.g., starspots, faculae) distort the stellar spectrum in transit and imprint wavelength-dependent biases on the planet-to-star radius ratio (…
Evaluating Habitability and Biosignature Detection on TOI-700 d: The Role of UV Environment and Atmospheric Pressure
Viktor Y. D. Sumida, Raissa Estrela, Adriana Valio
M dwarfs have long been prime targets in the search for habitable exoplanets, owing to their abundance in the galaxy and the relative ease of detecting Earth-sized worlds within th…
TOI-1173 A : The First Inflated Super-Neptune in a Wide Binary System
Jhon Yana Galarza, Thiago Ferreira, Diego Lorenzo-Oliveira +8
Among Neptunian mass exoplanets ( M), puffy hot Neptunes are extremely rare, and their unique combination of low mass and extended radii implies very low density ($…
Impact of M-dwarf Stellar Wind and Photoevaporation on the Atmospheric Evolution of Small Planets
Ashini Modi, Raissa Estrela, Adriana Valio
The evolution of a planet's atmosphere depends strongly on its host star's properties. When their host stars are younger, planets can experience stronger winds and EUV emissions. T…
Detection of Aerosols at Microbar Pressures in an Exoplanet Atmosphere
Raissa Estrela, Mark Swain, Gael Roudier +3
Formation of hazes at microbar pressures has been explored by theoretical models of exoplanet atmospheres to explain Rayleigh scattering and/or featureless transmission spectra, ho…
Detection of an Atmosphere on a Rocky Exoplanet
Mark R. Swain, Raissa Estrela, Gael M. Roudier +7
We report the detection of an atmosphere on a rocky exoplanet, GJ 1132 b, which is similar to Earth in terms of size and density. The atmospheric transmission spectrum was detected…
