The NASA Exoplanet Archive and Exoplanet Follow-up Observing Program: Data, Tools, and Usage

open access: yesThe Planetary Science Journal
The NASA Exoplanet Archive (NEA) and the Exoplanet Follow-up Observing Program service are two widely used resources for the exoplanet community. The NEA provides a complete and accurate accounting of exoplanetary systems published by NASA missions and ...

On Tides and Exoplanets

open access: yesProceedings of the International Astronomical Union, 2019
AbstractThis paper reviews the basic equations used in the study of the tidal variations of the rotational and orbital elements of a system formed by one star and one close-in planet as given by the creep tide theory and Darwin’s constant time lag (CTL) theory.

Detecting Exoplanet Transits with the Next Generation of X-Ray Telescopes

open access: yesThe Astronomical Journal
Detecting exoplanet transits at X-ray wavelengths would provide a window into the effects of high-energy irradiation on the upper atmospheres of planets.

Notes on exoplanets

open access: yesJournal of Physics: Conference Series, 2010
Our knowledge about exoplanets evolves rapidly. Here I give a short overview of some aspects of the exoplanet research and I also introduce shortly the reader to the Hungarian activities in the exoplanet field.

Hundreds of TESS Exoplanets Might Be Larger than We Thought

open access: yesThe Astrophysical Journal Letters
The radius of a planet is a fundamental parameter that probes its composition and habitability. Precise radius measurements are typically derived from the fraction of starlight blocked when a planet transits its host star.

Exoplanet Chemistry

open access: yesarXiv: Earth and Planetary Astrophysics, 2009
The terrestrial and gas-giant planets in our solar system may represent some prototypes for planets around other stars; the exoplanets because most stars have similar overall elemental abundances as our sun. The solar system planets represent at least four chemical planet types, depending on the phases that make them: Terrestrial-like planets made of ...

The Importance of Optical Wavelength Data on Atmospheric Retrievals of Exoplanet Transmission Spectra

open access: yesThe Astronomical Journal
Exoplanet transmission spectra provide rich information about the chemical composition, clouds, and temperature structure of exoplanet atmospheres. Most exoplanet transmission spectra only span infrared wavelengths (≳1 μ m), which can preclude crucial ...
