An H i interstellar bubble surrounding WR 85 and RCW 118
We analyze the distribution of the interstellar matter in the environs of the Wolf-Rayet star LSS 3982 (= WR 85, WN6+OB?) linked to the optical ring nebula RCW 118. Our study is based on neutral hydrogen 21cm-line data belonging to the Southern Galactic Plane Survey (SGPS). The analysis of the Hi data allowed the identification of a neutral hydrogen in-terstellar bubble related to WR 85 and the...
متن کاملSh 2 - 205 : I . The surrounding interstellar medium
We investigate the distribution of the interstellar matter in the environs of the H ii region Sh2-205, based on neutral hydrogen 21–cm line data and radio continuum images at 408 and 1420 MHz obtained from the CGPS, 12 CO (J=1→0) observations, high resolution IRAS data (HIRES), and MSX data. Sh2-205 can be separated in three independent optical structures: SH 149.25–0.0, SH 148.83–0.67, and LBN...
متن کاملShocked gas layers surrounding the WR nebula NGC 2359
NGC 2359 is a Wolf-Rayet (W-R) nebula partially bound by a rather dense and warm molecular cloud. We present the results derived from CO and 13 CO fully sampled maps of the molecular material with angular resolutions up to 12 ′′. We have detected three different velocity components, and determined their spatial distribution and physical properties. The kinematics, morphology, mass and density a...
متن کاملInfrared spectroscopy of young supernova remnants heavily interacting with the interstellar medium ⋆ I . Ionized species in RCW 103
ISO spectral observations of the supernova remnant RCW103 are presented. This object is the prototype of relatively young remnants ( 103 yr) with fast shocks (vs 1000 km/s) interacting with dense interstellar medium. The spectrum is dominated by prominent lines of [NeII], [SiII], [FeII] and other low excitation species which provide, for the first time, a simple and reliable estimate of the gas...
متن کاملInterstellar H(3)(+).
Protonated molecular hydrogen, H(3)(+), is the simplest polyatomic molecule. It is the most abundantly produced interstellar molecule, next only to H(2), although its steady state concentration is low because of its extremely high chemical reactivity. H(3)(+) is a strong acid (proton donor) and initiates chains of ion-molecule reactions in interstellar space thus leading to formation of complex...
