High - resolution radio observations of RCW 49
High-resolution radio continuum observations of the southern H II complex RCW 49 are presented. The observations were carried out with the Molonglo Observatory Synthesis Telescope (MOST) at 0.843 GHz, and the Australia Telescope Compact Array (ATCA) at 1.38 and 2.38 GHz. Two wind-blown shells have been discovered in the core region of RCW 49, the more massive of which surrounds the Westerlund 2...
متن کاملRCW 103 – Revisiting a cooling neutron star
Recent observations of the compact source embedded within the supernova remnant RCW 103 rekindle interest in the origin of this object’s emission. We contrast several models in which neutron-star cooling powers RCW 103. Specifically, either the presence of an accreted envelope or a sufficiently intense magnetic field can account for the X-ray emission from this object. Subject headings: stars: ...
متن کاملPulsar Near the Supernova Remnant RCW 103
Received ; accepted – 2 – ABSTRACT We report the detection of the radio pulsar counterpart to the 69 ms X-ray pulsar discovered near the supernova remnant RCW 103 (G332.4−0.4). Our detection confirms that the pulsations arise from a rotation-powered neutron star, which we name PSR J1617−5055. The observed barycentric period derivative confirms that the pulsar has a characteristic age of only 8 ...
متن کاملWork of a day-bed unit 1972-8.
From 1972 to 1978 inclusive 32 311 patients were managed in a 24-bedded day-bed unit in a district general hospital. The principal specialties using this were urology, gastroenterology, general surgery, gynaecology, haematology, orthopaedics, and radiology. Patient selection, a high standard of secretarial work, and good liaison with general practitioners, the community nursing service, and the...
متن کاملThe Embedded Massive Star Forming Region RCW 38
RCW 38 is a uniquely young (<1 Myr), embedded (AV ∼ 10) stellar cluster surrounding a pair of early O stars (∼O5.5) and is one of the few regions within 2 kpc other than Orion to contain over 1000 members. X-ray and deep near-infrared observations reveal a dense cluster with over 200 X-ray sources and 400 infrared sources embedded in a diffuse hot plasma within a 1 pc diameter. The central O st...
