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

open access: yesThe 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 ...

FORMATION OF CIRCUMBINARY PLANETS IN A DEAD ZONE [PDF]

open access: yesThe Astrophysical Journal, 2013
Circumbinary planets have been observed at orbital radii where binary perturbations may have significant effects on the gas disk structure, on planetesimal velocity dispersion, and on the coupling between turbulence and planetesimals. Here, we note that the impact of all of these effects on planet formation is qualitatively altered if the circumbinary ...

Habitability Properties of Circumbinary Planets [PDF]

open access: yesThe Astronomical Journal, 2017
Abstract It is shown that several habitability conditions (in fact, at least seven such conditions) appear to be fulfilled automatically by circumbinary planets of main-sequence stars (CBP-MS), whereas on Earth, these conditions are fulfilled only by chance.

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

open access: yesAdvances 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

Is There a Circumbinary Planet around NSVS 14256825? [PDF]

open access: bronzeThe Astronomical Journal, 2017
Abstract The cyclic behavior of (O–C) residuals of eclipse timings in the sdB+M eclipsing binary NSVS 14256825 was previously attributed to one or two Jovian-type circumbinary planets. We report 83 new eclipse timings that not only fill in the gaps in those already published but also extend the time span of the (O–C) diagram by three ...

Dusty Blue Supergiants: News from High‐Angular Resolution Observations

open access: yesAdvances 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

open access: yesAdvances 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.
