TESS Discovery of a Transiting Super-Earth in the $\pi$ Mensae System

, 2018
We report the detection of a transiting planet around $\pi$ Mensae (HD 39091), using data from the Transiting Exoplanet Survey Satellite (TESS). The solar-type host star is unusually bright (V=5.7) and was already known to host a Jovian planet on a ...

Identifying Exoplanet Candidates Using WaveCeptionNet

The Astronomical Journal
In this study, we propose a wavelet-transform-based light curve representation method and a CNN model based on Inception-v3 for fast classification of light curves, enabling the quick discovery of potentially interesting targets from massive data ...

Seismic constraints on rotation of Sun-like star and mass of exoplanet

, 2013
Rotation is thought to drive cyclic magnetic activity in the Sun and Sun-like stars. Stellar dynamos, however, are poorly understood owing to the scarcity of observations of rotation and magnetic fields in stars.

The Polar Orbit of TOI-2374 b, a Planet in the Neptunian Ridge

The Astronomical Journal
The “Neptunian ridge” is a recently identified peak in the frequency of planets with sizes between that of Neptune and Saturn orbiting their host stars with periods between 3 and 6 days.

A Comprehensive Analysis of Spitzer 4.5 μm Phase Curves of Hot Jupiters

The Astronomical Journal
Although exoplanetary science was not initially projected to be a substantial part of the Spitzer mission, its exoplanet observations set the stage for current and future surveys with JWST and Ariel.

A Direct Comparison between the Use of Double Gray and Multiwavelength Radiative Transfer in a General Circulation Model with and without Radiatively Active Clouds

The Astrophysical Journal
Inhomogeneous cloud formation and wavelength-dependent phenomena are expected to shape hot Jupiter atmospheres. We present a general circulation model with multiwavelength “picket fence” radiative transfer and radiatively active, temperature-dependent ...

WASP-21b: a hot-Saturn exoplanet transiting a thick disc star [PDF]

, 2010
We report the discovery of WASP-21b, a new transiting exoplanet discovered by the Wide Angle Search for Planets (WASP) Consortium and established and characterized with the FIES, SOPHIE, CORALIE and HARPS fiber-fed echelle spectrographs.

Early Accretion of Large Amounts of Solids for Directly Imaged Exoplanets

The Astrophysical Journal
As the number of planetary-mass objects (PMOs; ⪅13 M _Jupiter ) at wider separation (⪆10 au) grows, there is emerging evidence that they form differently from their higher-mass brown dwarf counterparts.

Astrophysics datamining in the classroom: Exploring real data with new software tools and robotic telescopes

, 2012
Within the efforts to bring frontline interactive astrophysics and astronomy to the classroom, the Hands on Universe (HOU) developed a set of exercises and platform using real data obtained by some of the most advanced ground and space observatories. The
