HATS-8b: A Low-Density Transiting Super-Neptune [PDF]

, 2015
HATS-8b is a low density transiting super-Neptune discovered as part of the HATSouth project. The planet orbits its solar-like G dwarf host (V=14.03 $\pm$ 0.10 and T$_{eff}$ =5679 $\pm$ 50 K) with a period of 3.5839 d.

Hubble Space Telescope Transmission Spectroscopy for the Temperate Sub-Neptune TOI-270 d: A Possible Hydrogen-rich Atmosphere Containing Water Vapor

The Astronomical Journal, 2023
TOI-270 d is a temperate sub-Neptune discovered by the Transiting Exoplanet Survey Satellite (TESS) around a bright ( J = 9.1 mag) M3V host star. With an approximate radius of 2 R _⊕ and equilibrium temperature of 350 K, TOI-270 d is one of the most ...

Bayesian analysis of exoplanet and binary orbits

, 2012
We introduce BASE (Bayesian astrometric and spectroscopic exoplanet detection and characterisation tool), a novel program for the combined or separate Bayesian analysis of astrometric and radial-velocity measurements of potential exoplanet hosts and ...

Validation of the Exoplanet Kepler-21b using PAVO/CHARA Long-Baseline Interferometry [PDF]

, 2012
We present long-baseline interferometry of the Kepler exoplanet host star HD179070 (Kepler-21) using the PAVO beam combiner at the CHARA Array. The visibility data are consistent with a single star and exclude stellar companions at separations ~1-1000 ...

VaTEST. II. Statistical Validation of 11 TESS-detected Exoplanets Orbiting K-type Stars

The Astronomical Journal, 2023
NASA’s Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission designed to find transiting exoplanets orbiting nearby bright stars. It has identified more than 329 transiting exoplanets, and almost 6000 candidates remain unvalidated. In

Asteroseismology of Exoplanet Host Stars

, 2015
Asteroseismology is among the most powerful observational tools to determine fundamental properties of stars. Space-based photometry has recently enabled the systematic detection of oscillations in exoplanet host stars, allowing a combination of ...
