An Effelsberg HI study of the ISM around WR 126, WR 154 and WR 155
(EDP Sciences, 2004-12)
The neutral hydrogen distribution has been studied in the direction of three Galactic Wolf-Rayet (WR) stars using the 100 m Effelsberg radio telescope. Cavities in the HI distribution, regions of low HI emissivity, are ...
The ISM around WR 152 and WR 153ab
(Universidad Nacional Autónoma de México. Instituto de Astronomía, 2008-12)
We analyzed the distribution of the interstellar matter in the environs of the WR stars WR 152 and WR 153ab, associated with ring nebulae in the Sh2-132 HII region. Our study is based on radio data (continuum, HI, and ...
Weather regimes in the South American sector and neighbouring oceans during winter
(Springer, 2003-04)
We classified 34 years of winter daily 500 hPa geopotential height patterns over the eastern South Pacific-South America-South Atlantic region using the K-means clustering method. We found a significant classification into ...
The ISM around WR Stars: WR152 and WR153ab
(Astronomical Society Of The Pacific, 2008-12)
We analyze the distribution of interstellar matter in the environs of the WR stars WR 152 and WR 153ab, associated with two different ring nebulae in the H ii region Sh2-132. We have detected the radio continuum and infrared ...
VLA radio continuum and IRAS observing of the ring nebulae around W 101 and W 113
(IOP Publishing, 2002-06)
We report radio continuum observations at 1465 MHz obtained with the Very Large Array (VLA) in the DnC configuration toward the ring nebulae associated with the stars WR 101 and WR 113, with resolutions of 3800 and 3000, ...
HI bubbles surrounding southern optical ring nebulae: Anon(WR 23) and RCW 52
(EDP Sciences, 2005-12)
We analyze the interstellar medium in the environs of two hot and massive stars, HD 92809 (= WR 23, WC6) and LSS 1887 (O8V), which ionize the optical ring nebulae Anon(WR 23) and RCW 52, respectively. Our analysis is based ...
