Young Binary Stars and Associated Disks

  journal={arXiv: Astrophysics},
The typical product of the star formation process is a binary star. Binaries have provided the first dynamical measures of the masses of pre-main-sequence (PMS) stars, providing support for the calibrations of PMS evolutionary tracks. Surprisingly, in some star-forming regions PMS binary frequencies are higher than among main-sequence solar-type stars. The difference in PMS and main-sequence binary frequencies is apparently not an evolutionary effect; recent attention has focussed on…

Binary star systems and extrasolar planets

For ten years, planets around stars similar to the Sun have been discovered, confirmed, and their properties studied. Planets have been found in a variety of environments previously thought

Formation, Dynamical Evolution, and Habitability of Planets in Binary Star Systems

A survey of currently known planet-hosting stars indicates that approximately 25% of extrasolar planetary systems are within dual-star environments. Several of these systems contain stellar

The Observation of Circumstellar Disks: Dust and Gas Components

Since the 1990's, protoplanetary disks and planetary disks have been intensively observed from the optical to the millimetre wavelength and many models have been developed to investigate their gas

Extreme Habitability: Formation of Habitable Planets in Systems with Close-in Giant Planets and/or Stellar Companions

With more than 260 extrasolar planetary systems discovered to-date, the search for habitable planets has found new grounds. Unlike our solar system, the stars of many of these planets are hosts to

Is multiplicity universal? : a study of multiplicity in the young moving groups

The young moving groups are collections of nearby (<200 pc), young (5-150 Myr) premain sequence stars; these stars offer us one of the best opportunities to characterise stellar multiplicity,

Molecular emission in regions of star formation

Recent observations show that young stars being formed eject matter at several tens of kilometers per second, in the form of 'jets' that impact the matter whose collapse is at the origin of the

Disks Around Young Binary Stars

Multiple star systems provide a complicated mix of conditions for planet formation. Whereas circumstellar disks around single stars are likely routine sites for planet formation, binary systems can

Effects of Chaotic Clearing in Planetary Systems

In this Chapter, major types of chaotic clearing effects in planetary systems and their subsystems are considered. Generally, the clearing effects consist in forming orbital zones free from low-mass


Tracing magnetic field is crucial as magnetic field plays an important role in many astrophysical processes. Earlier studies have demonstrated that ground state alignment (GSA) is an effective way to

Resonances, instabilities, and the chaotic behaviour caused by interaction of resonances play an essential role in the dynamics of planetary systems at various stages of their evolution. In concert



Star Formation Environments and the Distribution of Binary Separations

We have carried out K-band speckle observations of a sample of 114 X-ray-selected weak-line T Tauri stars in the nearby Scorpius-Centaurus OB association. We find that for binary T Tauri stars

The connection between submillimeter continuum flux and binary separation in young binaries: evidence of interaction between stars and disks

We present 800 micron continuum photometry of pre-main-sequence binary stars with projected separations a_p < 150 AU in the Sco-Oph star-forming region. Combining our observations with published 1300

Pre-Main-Sequence Binary Stars

The observational study of pre-main-sequence (PMS) binary stars is in many ways a very young field; most PMS binaries known today were discovered in the past decade. Nonetheless, T Tauri stars have

A Survey for Circumstellar Disks around Young Stellar Objects

Results are presented from a survey for 1.3 mm radiation toward 86 stars in the Taurus-Auriga dark clouds, including classical T Tauri stars, stars in T associations, and a few weak emission-line

The occurrence and properties of disks around young stars

The paper discusses the occurrence and properties of disks around young stars, emphasizing in particular how these may relate to planet formation and the evolution of the solar system. The global

A Connection between Submillimeter Continuum Flux and Separation in Young Binaries

We have made sensitive 800-micron continuum observations of low-mass, pre-main sequence (PMS) binary stars with projected separations less than 25 AU in Taurus-Auriga to study disks in the young

Low-mass binaries in the young cluster IC 348: implications for binary formation and evolution

We report on a near-infrared adaptive optics survey of a sample of 66 low-mass members of the pre-main sequence stellar cluster IC 348. We find 12 binary systems in the separation range 0.1-8.0

The Multiplicity of Pre-Main-Sequence Stars in Southern Star-forming Regions

High-resolution studies of young stars in the star-forming regions of Taurus and Ophiuchus have revealed a large population of multiple star systems. To test how applicable this earlier result is for

Are Both Stars in a Classic T Tauri Binary Classic T Tauri Stars?

Large near-IR color excesses and emission-line spectra indicate the presence of optically thick circumstellar accretion disks and active boundary layers in young stars. We investigate whether this

Multiplicity among T Tauri stars in OB and T associations: Implications for binary star formation

We present first results of a survey for companions among X-ray selected pre-main sequence stars, most of them being weak-line T Tauri stars (WTTS). These T Tauri stars have been identified in the
