Search for (sub)stellar Companions of Exoplanet Hosts by Exploring the Second ESA-Gaia Data Release
Frontiers in Astronomy and Space Sciences, 2021 We present the latest results of an ongoing multiplicity survey of exoplanet hosts, which was initiated at the Astrophysical Institute and University Observatory Jena, using data from the second data release of the ESA-Gaia mission.

The Ultraviolet Radiation Environment Around M dwarf Exoplanet Host Stars [PDF]
, 2012 The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres. At present, little observational or theoretical basis exists for understanding the ultraviolet spectra of M ...

The Habitable Zone and Extreme Planetary Orbits [PDF]
, 2012 The Habitable Zone for a given star describes the range of circumstellar distances from the star within which a planet could have liquid water on its surface, which depends upon the stellar properties.

X-Ray studies of exoplanet systems [PDF]
, 2022 X-rays are integral to furthering our knowledge of exoplanetary systems. In this work we discuss the use of X-ray observations to understand star-planet interac- tions, mass-loss rates of an exoplanet’s atmosphere and the study of an exoplanet’s atmospheric components using future X-ray spectroscopy.

Solar System Physics for Exoplanet Research
Publications of the Astronomical Society of the Pacific, 2020 Abstract Over the past three decades, we have witnessed one of the great revolutions in our understanding of the cosmos—the dawn of the Exoplanet Era. Where once we knew of just one planetary system (the solar system), we now know of thousands, with new systems being announced on a weekly basis.

Extrasolar planets in stellar multiple systems
, 2012 Analyzing exoplanets detected by radial velocity or transit observations, we determine the multiplicity of exoplanet host stars in order to study the influence of a stellar companion on the properties of planet candidates.

UniverseThe distribution of period ratios for 580 known two-planet systems is apparently nonuniform, with several sharp peaks and troughs. In particular, the vicinity of the 2:1 commensurability seems to have a deficit of systems.

The observation of exoplanet transit events in China
EPJ Web of Conferences, 2011 We have carried out a research project on the exoplanet transit events at Yunnan Observatory. By using CCD cameras attached to 1m telescope of Yunnan Observatory and 85cm telescope of Xinglong station, NAOC, a group of exoplanet systems with transit ...

Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems
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 ...
