Stability analysis of three exoplanet systems [PDF]

open access: yesMonthly 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 ...

Solar System Physics for Exoplanet Research [PDF]

open access: yesPublications 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.

Radio-loud Exoplanet-exomoon Survey: GMRT Search for Electron Cyclotron Maser Emission [PDF]

open access: yesThe 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 [PDF]

open access: yesAstronomy & Astrophysics
Aims. 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 [PDF]

open access: yesEPJ 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 ...

Spectroscopic Follow-up of Gaia Exoplanet Candidates: Impostor Binary Stars Invade the Gaia DR3 Astrometric Exoplanet Candidates [PDF]

open access: yesThe Astronomical Journal, 2023
In this paper, we report on the follow-up of six potential exoplanets detected with Gaia astrometry and provide an overview of what is currently known about the nature of the entire Gaia astrometric exoplanet candidate sample, 72 systems in total.

Validation of TOI-1221 b: A Warm Sub-Neptune Exhibiting Transit Timing Variations around a Sun-like Star

open access: yesThe Astronomical Journal, 2023
We present a validation of a long-period ( ${91.68278}_{-0.00041}^{+0.00032}$ days) transiting sub-Neptune planet, TOI-1221 b (TIC 349095149.01), around a Sun-like ( m _V = 10.5) star.

Kepler-80 Revisited: Assessing the Participation of a Newly Discovered Planet in the Resonant Chain

open access: yesThe Astronomical Journal, 2023
In this paper, we consider the chain of resonances in the Kepler-80 system and evaluate the impact that the additional member of the resonant chain discovered by Shallue & Vanderburg has on the dynamics of the system and the physical parameters that can ...

Scaling K2. V. Statistical Validation of 60 New Exoplanets From K2 Campaigns 2–18

open access: yesThe Astronomical Journal, 2022
The NASA K2 mission, salvaged from the hardware failures of the Kepler telescope, has continued Kepler’s planet-hunting success. It has revealed nearly 500 transiting planets around the ecliptic plane, many of which are the subject of further study, and ...
