ALMA returns to Boomerang Nebula:Companion star provides chilling power of 'Coldest Object in the Universe'
ALMA Boomerang Nebula Companion star chilling power Coldest Object in the Universe
2017/7/21
An ancient, red giant star in the throes of a frigid death has produced the coldest known object in the cosmos — the Boomerang Nebula. How this star was able to create an environment strikingly colder...
VARIABLE O VI AND N V EMISSION FROM THE X-RAY BINARY LMC X-3: HEATING OF THE BLACK HOLE COMPANION*
Cosmic Origins
2014/12/22
Based on high-resolution ultraviolet spectroscopy obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) and the Cosmic Origins Spectrograph, we present new detections of O VI and N V emissio...
THE SINGLE-DEGENERATE BINARY ORIGIN OF TYCHO'S SUPERNOVA AS TRACED BY THE STRIPPED ENVELOPE OF THE COMPANION
X-ray arc Tycho's supernova
2014/12/20
We propose that a nonthermal X-ray arc inside the remnant of Tycho's supernova (SN) represents the interaction between the SN ejecta and the companion star's envelope lost in the impact of the explosi...
Using a vector vortex coronagraph behind the 1.5-m well-corrected subaperture (WCS) at Palomar, we detected a second object very close to \epsilon Cephei, a \delta Scuti F0 IV star. The candidate comp...
Discovery of a Companion at the L/T Transition with the Wide-field Infrared Survey Explorer
Discovery Companion Transition with Infrared Survey Explorer
2011/9/30
We report the discovery of a substellar companion to the nearby solar-type star HD 46588 (F7V, 17.9 pc, ~3 Gyr). HD 46588 B was found through a survey for common proper motion companions to nearby sta...
The Hyperactive L Dwarf 2MASS J13153094-2649513: Continued Emission and a Brown Dwarf Companion
Hyperactive: Continued Emission Dwarf Companion
2011/9/29
We report new observations of the unusually active, high proper motion L5e dwarf 2MASS J13153094-2649513. Optical spectroscopy with Magellan/MagE reveals persistent nonthermal emission, with narrow H ...
Sparse aperture masking at the VLT I. Faint companion detection limits for the two debris disk stars HD 92945 and HD 141569
Instrumentation: high angular resolution – Stars: planetary systems – Stars: individual
2011/9/29
Observational data on companion statistics around young stellar systems is needed to flesh out the formation pathways for extrasolar planets and brown dwarfs. Aperture masking is a new technique that ...
A white dwarf companion to the relativistic pulsar PSR J1141-6545
methods photometry – binaries close – pulsars general – stars neutron white dwarfs – individual PSRJ1141− 6545
2010/11/10
Pulsars with compact companions in close eccentric orbits are unique laboratories for testing general relativity and alternative theories of gravity. Moreover, they are excellent targets for future gr...
The optical companion to the binary millisecond pulsar J1824-2452H in the globular cluster M28
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/31
We report on the optical identification of the companion star to the eclipsing millisecond pulsar PSR J1824-2452H in the galactic globular cluster M28 (NGC 6626). This star is at only 0.2" from the no...
Transiting exoplanets from the CoRoT space mission. XV. CoRoT-15b: a brown dwarf transiting companion
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/23
We report the discovery by the CoRoT space mission of a transiting brown dwarf orbiting a F7V star with an orbital period of 3.06 days. CoRoT-15b has a radius of 1.12 +0.30 -0.15 Rjup, a mass of 63.3 ...
Moon Rock Gains Traveling Companion for Historic Return to Space
