SPOTS: The Search for Planets Orbiting Two Stars. I. Survey description and first observations

, 2014
Direct imaging surveys for exoplanets commonly exclude binary stars from their target lists, leaving a large part of the overall planet demography unexplored.

Orbital and Atmospheric Modeling of H ii 1348B: An Eccentric Young Substellar Companion in the Pleiades

The Astronomical Journal
Brown dwarfs with known physical properties (e.g., age and mass) are essential for constraining models of the formation and evolution of substellar objects.

On the migration of protoplanets embedded in circumbinary disks

, 2007
We present the results of hydrodynamical simulations of low mass protoplanets embedded in circumbinary accretion disks. The aim is to examine the migration and long term orbital evolution of the protoplanets, in order to establish the stability ...

A new approach for probing circumbinary disks

, 2009
Circumbinary disks are considered to exist in a wide variety of astrophysical objects, e.g., young binary stars, protoplanetary systems, and massive binary black hole systems in active galactic nuclei (AGNs).

An algorithm for photometric identification of transiting circumbinary planets [PDF]

Monthly Notices of the Royal Astronomical Society, 2008
Transiting planets manifest themselves by a periodic dimming of their host star by a fixed amount. On the other hand, light curves of transiting circumbinary (CB) planets are expected to be neither periodic nor to have a single depth while in transit.

Disk Evolution in Young Binaries: from Observations to Theory [PDF]

, 2006
The formation of a binary system surrounded by disks is the most common outcome of stellar formation. Hence studying and understanding the formation and the evolution of binary systems and associated disks is a cornerstone of star formation science ...

Too fast to be single: Tidal evolution and photometric identification of stellar and planetary companions

The Open Journal of Astrophysics
Many stars exist in binary or multiple systems where tidal interactions modify rotational evolution. In single stars, Many stars, including those in binary or multiple systems, exhibit modified rotational evolution due to tidal interactions.
