Two New Candidate Planets in Eccentric Orbits [PDF]

, 1999
Doppler measurements of two G-type main-sequence stars, HD210277 and HD168443, reveal Keplerian variations that imply the presence of companions with masses (M sin i) of 1.28 and 5.04 M_Jup and orbital periods of 437 d and 58 d, respectively.

The role of the initial surface density profiles of the disc on giant planet formation: comparing with observations [PDF]

, 2003
In order to explain the main characteristics of the observed population of extrasolar planets and the giant planets in the Solar System, we need to get a clear understanding of which are the initial conditions that allowed their formation. To this end we

The Formation and Dynamics of Super-Earth Planets

, 2013
Super-Earths, objects slightly larger than Earth and slightly smaller than Uranus, have found a special place in exoplanetary science. As a new class of planetary bodies, these objects have challenged models of planet formation at both ends of the ...

Detection and Characterization of Extrasolar Planets through Doppler Spectroscopy

, 2009
Over 300 extrasolar planets have been found since 1992, showing that planetary systems are common and exhibit an outstanding variety of characteristics.

TESS Giants Transiting Giants. III. An Eccentric Warm Jupiter Supports a Period−Eccentricity Relation for Giant Planets Transiting Evolved Stars

The Astronomical Journal, 2023
The fate of planets around rapidly evolving stars is not well understood. Previous studies have suggested that, relative to the main-sequence population, planets transiting evolved stars ( P < 100 days) tend to have more eccentric orbits. Here we present

A theoretical look at the direct detection of giant planets outside the Solar System

, 2005
Astronomy is at times a science of unexpected discovery. When it is, and if we are lucky, new intellectual territories emerge to challenge our views of the cosmos.

Early planet formation as a trigger for further planet formation [PDF]

, 1999
Recent discoveries of extrasolar planets at small orbital radii, or with significant eccentricities, indicate that interactions between massive planets and the disks of gas and dust from which they formed are vital for determining the final shape of ...

Superhabitable Planets Around Mid‐Type K Dwarf Stars Enhance Simulated JWST Observability and Surface Habitability

Astronomische Nachrichten, Volume 346, Issue 2, February 2025.
ABSTRACT In our search for life beyond the Solar System, certain planetary bodies may be more conducive to life than Earth. However, the observability of these “superhabitable” (SH) planets in the habitable zones around K dwarf stars has not been fully modeled. This study addresses this gap by modeling the atmospheres of SH exoplanets.

Accretion of Planetary Material onto Host Stars

, 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 ...
