A SEARCH FOR RADIO PULSARS IN THE NORTHERN SKY: DISCOVERY OF A PULSAR IN A UNIQUE BINARY SYSTEM
Search Radio pulsar The sky The pulsar. A binary system
2014/12/10
A sensitive search for pulsars has been conducted using the 92-meter transit telescope of the National Radio Astronomy Observatory. Nearly 50% of the sky north of +20(DEGREES) declination was searched...
Elemental abundance differences in the 16 Cygni binary system: a signature of gas giant planet formation?
Elemental abundance differences signature planet formation
2011/10/20
The atmospheric parameters of the components of the 16Cygni binary system, in which the secondary has a gas giant planet detected, are measured accurately using high quality observational data. Abunda...
Multi-wavelength observations of the young binary system Haro 6-10: The case of misaligned discs
Binary stars - Star Formation - Haro 6-10
2011/10/17
Context. We present a multi-wavelength, high-resolution observational survey of the young binary system Haro 6-10 (GV Tau, IRAS 04263+2426), which is harbouring one of the few known infrared companion...
Modelling interaction of relativistic and non-relativistic winds in binary system PSR B1259-63/SS2883 - II. Impact of magnetization and anisotropy of the pulsar wind
HD – shock waves - pulsars: binaries
2011/10/19
In this paper, we present a numerical study of the properties of the flow produced by the collision of a magnetized anisotropic pulsar wind with its environment in binary system. We compare the impact...
Discovery of a stripped red giant core in a bright eclipsing binary system
binaries: spectroscopic – binaries: individual: KOI-81 – stars: individual 1SWASP J024743.37− 251549.2
2011/10/19
We have identified a star in the WASP archive photometry with an unusual lightcurve due to the total eclipse of a small, hot star by an apparently normal A-type star and with an orbital period of only...
Radio Imaging of the NGC 1333 IRAS 4A Region: Envelope, Disks, and Outflows of a Protostellar Binary System
ISM: individual (NGC 1333 IRAS 4A) — ISM: jets outfl ows — ISM: binaries: general— stars: formation
2011/10/12
The NGC 1333 IRAS 4A protobinary was observed in the 1.3 cm and 6.9 mm continuum and the ammonia and SiO lines, with an angular resolution of about 0.4 arcseconds. The continuum maps show the circumst...
