Hunting for Cold Exoplanets via Microlensing

Comptes Rendus. Physique, 2023
Microlensing can detect planets at distances ranging from a few hundred parsecs all the way to the Galactic center. The maximum sensitivity is reached for systems that are located half way to the galactic center, with planets orbiting the lens star at a ...

The Resilience of Habitable Climates Around Circumbinary Stars

Journal of Geophysical Research: Planets, Volume 125, Issue 9, September 2020., 2020
Abstract Here we use a 3‐D climate system model to study the habitability of Earth‐like planets orbiting in circumbinary systems. In the most extreme cases, Earth‐like planets in circumbinary systems could experience variations in the incident stellar flux of up to ~50% on ~100‐day timescales.

Frame-Dragging in Extrasolar Circumbinary Planetary Systems

Universe, 2022
Extrasolar circumbinary planets are so called because they orbit two stars instead of just one; to date, an increasing number of such planets have been discovered with a variety of techniques.

BEBOP V. Homogeneous stellar analysis of potential circumbinary planet hosts [PDF]

Monthly notices of the Royal Astronomical Society
Planets orbiting binary systems are relatively unexplored compared to those around single stars. Detections of circumbinary planets and planetary systems offer a first detailed view into our understanding of circumbinary planet formation and dynamical ...

On the potential origin of the circumbinary planet Delorme 1 (AB)b [PDF]

Monthly notices of the Royal Astronomical Society
Many circumbinary gas giant planets have been recently discovered. The formation mechanism of circumbinary planets on wide orbits is unclear. We investigate the formation of Delorme 1 (AB)b, a $13 \pm 5 \ \mathrm{ M_J}$ planet, orbiting its host binary

Terrestrial planet formation in a circumbinary disc around a coplanar binary [PDF]

Monthly notices of the Royal Astronomical Society, 2021
With N-body simulations, we model terrestrial circumbinary planet (CBP) formation with an initial surface density profile motivated by hydrodynamic circumbinary gas disc simulations.

Near-infrared Accretion Signatures from the Circumbinary Planetary-mass Companion Delorme 1 (AB)b

The Astrophysical Journal Letters, 2022
Accretion signatures from bound brown dwarf and protoplanetary companions provide evidence for ongoing planet formation, and accreting substellar objects have enabled new avenues to study the astrophysical mechanisms controlling the formation and ...

Equilibrium Points and Related Periodic Motions in the Restricted Three‐Body Problem with Angular Velocity and Radiation Effects

Advances in Astronomy, Volume 2015, Issue 1, 2015., 2015
The paper deals with a modification of the restricted three‐body problem in which the angular velocity variation is considered in the case where the primaries are sources of radiation. In particular, the existence and stability of its equilibrium points in the plane of motion of the primaries are studied. We find that this problem admits the well‐known

Dusty Blue Supergiants: News from High‐Angular Resolution Observations

Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014
An overview is presented of the recent advances in understanding the B[e] phenomenon among blue supergiant stars in light of high‐angular resolution observations and with an emphasis on the results obtained by means of long baseline optical stellar interferometry.

Possibility of Detection of Exomoons with Inclined Orbits Orbiting Pulsar Planets Using the Time‐of‐Arrival Analysis

Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014
The perturbation caused by planet‐moon binarity on the time‐of‐arrival (TOA) signal of a pulsar with an orbiting planet is derived for the case of the orbit of the planet‐moon system inclined of an angle α with respect to the plane of the orbit of the planet‐moon barycenter around the pulsar.
