Exoplanet Volatile Carbon Content as a Natural Pathway for Haze Formation [PDF]
The Astrophysical Journal Letters, 2023 We explore terrestrial planet formation with a focus on the supply of solid-state organics as the main source of volatile carbon. For the water-poor Earth, the water ice line, or ice sublimation front, within the planet-forming disk has long been a key ...

Haze Formation in Warm H2-rich Exoplanet Atmospheres [PDF]
The Planetary Science Journal, 2020 New observing capabilities coming online over the next few years will provide opportunities for characterization of exoplanet atmospheres. However, clouds/hazes could be present in the atmospheres of many exoplanets, muting the amplitude of spectral ...

THE IMPRINT OF EXOPLANET FORMATION HISTORY ON OBSERVABLE PRESENT-DAY SPECTRA OF HOT JUPITERS [PDF]
The Astrophysical Journal, 2016 The composition of a planet’s atmosphere is determined by its formation, evolution, and present-day insolation. A planet’s spectrum therefore may hold clues on its origins.

Sulfur-driven haze formation in warm CO2-rich exoplanet atmospheres [PDF]
Nature Astronomy, 2020 Sulfur gases substantially affect the photochemistry of planetary atmospheres in our Solar System, and are expected to be important components in exoplanet atmospheres.

A giant exoplanet orbiting a very-low-mass star challenges planet formation models [PDF]
Science, 2019 A small star hosts a big planet M dwarfs, the most common type of star, are low-mass objects that emit most of their faint light in the near-infrared, making it difficult to detect any orbiting exoplanets. Morales et al.

Aerosols in Exoplanet Atmospheres [PDF]
Journal of Geophysical Research: Planets, 2021 Observations of exoplanet atmospheres have shown that aerosols, like in the Solar System, are common across a variety of temperatures and planet types. The formation and distribution of these aerosols are inextricably intertwined with the composition and thermal structure of the atmosphere.

Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems [PDF]
The Astronomical Journal, 2023 The geometries of near-resonant planetary systems offer a relatively pristine window into the initial conditions of exoplanet systems. Given that near-resonant systems have likely experienced minimal dynamical disruptions, the spin–orbit orientations of ...

PLANETARY POPULATIONS IN THE MASS-PERIOD DIAGRAM: A STATISTICAL TREATMENT OF EXOPLANET FORMATION AND THE ROLE OF PLANET TRAPS [PDF]
, 2013 The rapid growth of observed exoplanets has revealed the existence of several distinct planetary populations in the mass–period diagram. Two of the most surprising are (1) the concentration of gas giants around 1 AU and (2) the accumulation of a large ...

Early Release Science of the exoplanet WASP-39b with JWST NIRCam. [PDF]
Nature, 2023 Time-series observations from the JWST of the transiting exoplanet WASP-39b show gaseous water in the planet’s atmosphere and place an upper limit on the abundance of methane.
