The CARMENES search for exoplanets around M dwarfs [PDF]
Astronomy & Astrophysics, 2020 We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, mb = 30.8 ± 1.5M⊕, Rb = 4.7 ± 0.3 R⊕) located in the “hot Neptune desert”. Confirmation of the TESS Object of Interest (TOI 442.01) was achieved with radial-velocity follow-up ...

Water on Hot Rocky Exoplanets [PDF]
, 2021 Data suggest that most rocky exoplanets with orbital period p < 100 days (“hot” rocky exoplanets) formed as gas-rich sub-Neptunes that subsequently lost most of their envelopes, but whether these rocky exoplanets still have atmospheres is unknown.

Physical Review D, 2023 The prevailing assumption is that all exoplanets are made of ordinary matter. However, we propose an unconventional possibility that some exoplanets could be made of dark matter, which we name "dark exoplanets." In this paper, we explore methods to search for dark exoplanets, including the mass-radius relation, spectroscopy, missing transit, and ...

Aerosol composition of hot giant exoplanets dominated by silicates and hydrocarbon hazes [PDF]
, 2020 Aerosols are common in the atmospheres of exoplanets across a wide swath of temperatures, masses and ages 1 – 3 . These aerosols strongly impact observations of transmitted, reflected and emitted light from exoplanets, obfuscating our understanding of ...

ExoMiner: A Highly Accurate and Explainable Deep Learning Classifier That Validates 301 New Exoplanets [PDF]
Astrophysical Journal, 2021 The Kepler and Transiting Exoplanet Survey Satellite (TESS) missions have generated over 100,000 potential transit signals that must be processed in order to create a catalog of planet candidates.

High Accuracy Molecular Line Lists for Studies of Exoplanets and Other Hot Atmospheres
Frontiers in Astronomy and Space Sciences, 2022 The desire to characterize and model the atmospheres of the many extrasolar planets that have been discovered over the last three decades is a major driver of current astronomy.

The EBLM Project—From False Positives to Benchmark Stars and Circumbinary Exoplanets
Universe, 2023 The EBLM project aims to characterise very-low-mass stars that are companions to solar-type stars in eclipsing binaries. We describe the history and motivation for this project, the methodology we use to obtain the precise mass, radius, and effective ...

The Astrophysical Journal Supplement Series, 2023 Characterizing the interiors of rocky exoplanets is important to understand planetary populations and further investigate planetary habitability. New observable constraints and inference techniques have been explored for this purpose.

Possibilities for an Aerial Biosphere in Temperate Sub Neptune-Sized Exoplanet Atmospheres
Universe, 2021 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 for observation with planned next-generation telescopes.
