Triggered star formation in a molecular shell created by a SNR?

Autor: Cichowolski, Silvina, Pineault, Serge, Gamen, Roberto, Arnal, E. Marcelo, Suad, Laura A., Ortega, Martin E.

We present a study of a new molecular shell, G126.1-0.8-14, using available multiwavelegth Galactic plane surveys and optical Gemini observations. A well defined shell-like structure is observed in the CO(1--0) line emission at (l,b) = (126.1, -0.8),

The SNR G106.3+2.7 and its Pulsar Wind Nebula: relics of triggered star formation in a complex environment

Autor: Kothes, Roland, Uyaniker, Bulent, Pineault, Serge

We propose that the pulsar nebula associated with the pulsar J2229+6114 and the supernova remnant (SNR) G106.3+2.7 are the result of the same supernova explosion. The whole structure is located at the edge of an HI bubble with extended regions of mol

The ISM around WR 152 and WR 153ab

Autor: Cappa, Cristina Elisabeth, Vasquez, Javier, Arnal, Edmundo Marcelo, Cichowolski, Silvina, Pineault, Serge

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 CO(1-0) observations) and images

Massive stars are known to have a profound impact on their surroundings through their high ionizing radiation, their strong stellar winds, and their eventual final explosion as supernovae. Within the area surveyed by the CGPS project there are 87 O-t

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 ∼38″ and 30″, respectively. IRAS image
