The Orbital Geometries and Stellar Obliquities of Exoplanet-hosting Multistar Systems
The Astronomical JournalThe current orbital geometries of exoplanet systems offer a fossilized record of the systems’ dynamical histories. A particularly rich set of dynamical mechanisms is available to exoplanets residing in multistar systems, which may have their evolution ...

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 ...

Solar System Physics for Exoplanet Research [PDF]
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.

Stability analysis of three exoplanet systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The orbital solutions of published multiplanet systems are not necessarily dynamically stable on time-scales comparable to the lifetime of the system as a whole. For this reason, dynamical tests of the architectures of proposed exoplanetary systems are a critical tool to probe the stability and feasibility of the candidate ...

On the Ordering of Exoplanet Systems
The Astrophysical JournalWe present a comprehensive analysis of planetary radius ordering within multiplanet systems, namely their ordinal position with respect to their size in a given system, utilizing data from the NASA Exoplanet Archive. In addition, we consider not only the

Radio-loud Exoplanet-exomoon Survey: GMRT Search for Electron Cyclotron Maser Emission [PDF]
The Astronomical Journal, 2022 We conducted the first dedicated search for signatures of exoplanet–exomoon interactions using the Giant Metrewave Radio Telescope (GMRT) as part of the radio-loud exoplanet-exomoon survey.

Polarimetry of exoplanet-exomoon systems
Astronomy & AstrophysicsAims. We investigated the potential of polarimetric observations in the optical wavelength range for the detection of exomoons and the characterization of exoplanet-exomoon systems. Methods. Using the three-dimensional Monte Carlo radiative transfer code POLARIS, we calculated flux and polarization phase curves of Earth-like exoplanets with a satellite

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 ...
