Models of Star-Planet Magnetic Interaction

open access: yes, 2017
Magnetic interactions between a planet and its environment are known to lead to phenomena such as aurorae and shocks in the solar system. The large number of close-in exoplanets that were discovered triggered a renewed interest in magnetic interactions ...

Why exomoons must be rare? [PDF]

open access: yesarXiv, 2017
The problem of the search for the satellites of the exoplanets (exomoons) is discussed recently. There are very many satellites in our Solar System. But in contrary of our Solar system, exoplanets have significant eccentricity. In process of planetary migration, exoplanets can cross some resonances with following growth of their orbital eccentricity ...

Super-Earths: A New Class of Planetary Bodies

open access: yes, 2011
Super-Earths, a class of planetary bodies with masses ranging from a few Earth-masses to slightly smaller than Uranus, have recently found a special place in the exoplanetary science.

The debris disk - terrestrial planet connection

open access: yes, 2011
The eccentric orbits of the known extrasolar giant planets provide evidence that most planet-forming environments undergo violent dynamical instabilities.

Accretion of Planetary Material onto Host Stars

open access: yes, 2017
Accretion of planetary material onto host stars may occur throughout a star's life. Especially prone to accretion, extrasolar planets in short-period orbits, while relatively rare, constitute a significant fraction of the known population, and these ...

A Testbed for Tidal Migration: The 3D Architecture of an Eccentric Hot Jupiter HD 118203 b Accompanied by a Possibly Aligned Outer Giant Planet

open access: yesThe Astronomical Journal
Characterizing outer companions to hot Jupiters plays a crucial role in deciphering their origins. We present the discovery of a long-period giant planet, HD 118203 c ( ${m}_{c}={11.79}_{-0.63}^{+0.69}\ {M}_{{\rm{J}}}$ , ${a}_{c}={6.28}_{-0.11}^{+0.10 ...

Searching for Snapshots of Giant Exoplanet Migration

open access: yes
NEID, an extreme precision Doppler spectrograph on the WIYN 3.5-meter Telescope at Kitt Peak National Observatory (a partnership between Indiana University, University of Wisconsin-Madison, Pennsylvania State University, Princeton University,Purdue University, NSF’s NOIRLab, and NASA), is helping unravel the origin of hot Jupiters.
