The ExoTETHyS Package: Tools for Exoplanetary Transits around Host Stars [PDF]
Astronomical Journal, 2019 We present here the first release of the open-source python package ExoTETHyS (stable: https://zenodo.org/badge/latestdoi/169268509, development version: https://github.com/ucl-exoplanets/ExoTETHyS/), which aims to provide a stand-alone set of tools for ...

SSRN Electronic Journal, 2020 How do foreign powers disengage from a conflict? We study this issue by examining the recent, large-scale security transition from international troops to local forces in the ongoing civil conflict in Afghanistan. We construct a new dataset that combines information on this transition process with declassified conflict outcomes and previously ...

Detecting Exoplanet Transits through Machine-learning Techniques with Convolutional Neural Networks [PDF]
Publications of the Astronomical Society of the Pacific, 2019 A machine-learning technique with two-dimension convolutional neural network is proposed for detecting exoplanet transits. To test this new method, five different types of deep-learning models with or without folding are constructed and studied.

On the Observability of Individual Population III Stars and Their Stellar-mass Black Hole Accretion Disks through Cluster Caustic Transits [PDF]
, 2018 We summarize panchromatic Extragalactic Background Light data to place upper limits on the integrated near-infrared surface brightness (SB) that may come from Population III stars and possible accretion disks around their stellar-mass black holes (BHs ...

Transits of Inclined Exomoons—Hide and Seek and an Application to Kepler-1625 [PDF]
Astrophysical Journal, 2019 A Neptune-sized exomoon candidate was recently announced by Teachey & Kipping, orbiting a 287 day gas giant in the Kepler-1625 system. However, the system is poorly characterized and needs more observations to be confirmed, with the next potential ...

Geophysical Observations of Phobos Transits by InSight
Geophysical Research Letters, 2020 Since landing on Mars, the NASA InSight lander has witnessed eight Phobos and one Deimos transits. All transits could be observed by a drop in the solar array current and the surface temperature, but more surprisingly, for several ones, a clear signature

Predicted Yield of Transits of Known Radial Velocity Exoplanets from the TESS Primary and Extended Missions [PDF]
Publications of the Astronomical Society of the Pacific, 2018 Radial velocity (RV) surveys have detected hundreds of exoplanets through their gravitational interactions with their host stars. Some will be transiting, but most lack sufficient follow-up observations to confidently detect (or rule out) transits.

Transitive and fully transitive groups [PDF]
Proceedings of the American Mathematical Society, 1998 The notions of transitivity and full transitivity for abelian pgroups were introduced by Kaplansky in the 1950s. Important classes of transitive and fully transitive p-groups were discovered by Hill, among others. Since a 1976 paper by Corner, it has been known that the two properties are independent of one another.

Exoplanet transits with next-generation radio telescopes [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Nearly everything we know about extrasolar planets to date comes from optical astronomy. While exoplanetary aurorae are predicted to be bright at low radio frequencies (< 1 GHz), we consider the effect of an exoplanet transit on radio emission from the ...
