Optical Spectroscopy of IRAS 02091 + 6333 ⋆
We present a detailed spectroscopic investigation, spanning four winters, of the asymptotic giant branch (AGB) star IRAS 02091+6333. Zijlstra & Weinberger (2002) found a giant wall of dust around this star and modelled this unique phenomenon. However their work suffered from the quality of the optical investigations of the central object. Our spectroscopic investigation allowed us to define the...
متن کاملOPTICAL SPECTROSCOPY OF THE IRAS 1-Jy SAMPLE OF ULTRALUMINOUS INFRARED GALAXIES
This paper discusses the optical spectroscopic properties of the IRAS 1-Jy sample (f60 > 1 Jy) of ultraluminous infrared galaxies (ULIGs: Lir > 10 12 L⊙; Ho = 75 km s −1 Mpc and qo = 0). One hundred and eight of the 118 1-Jy ULIGs have been observed at ∆λ = 8.3 Å resolution over the wavelength range ∼ 4500 Å – 8900 Å. These data are combined with large, previously published sets of optical spec...
متن کاملNear-infrared photometry and optical spectroscopy of IRAS sources in the Small Magellanic Cloud
Near-infrared photometry is obtained of 30 IRAS sources in the direction of the Small Magellanic Cloud selected to be possible AGB stars. Low resolution 4000 to 10 000 Å spectroscopy is presented for 10 of them, plus two AGB stars in the LMC. Improved IRAS fluxes are obtained using the gipsy package. Based on the optical spectra and analyses of colour-colour diagrams 9 are confirmed or likely c...
متن کاملThe Iras 1-jy Sample of Ultraluminous Infrared Galaxies: Ii. Optical Spectroscopy
This is the second paper in a series discussing the properties of ultraluminous infrared galaxies (ULIGs: Lir > 10 12 L⊙; Ho = 75 km s −1 Mpc and qo = 0.0) from the 1-Jy sample of Kim (1995). This paper presents the first results of a spectroscopic survey at optical wavelengths of a randomly selected subset of 45 ULIGs from Kim & Sanders (1997). These new data are combined with previous data fr...
متن کاملOptical Properties of 4248 IRAS Galaxies
We have investigated optical properties of 4248 infrared galaxies (IRGs) by positionally matching data from the Infrared Astronomical Satellite (IRAS) and the Sloan Digital Sky Survey Data Release 3 (SDSS DR3). Due to the large sky area coverage of both surveys, we have obtained an opportunity to study an unprecedentedly large number of 4248 infrared galaxies spanning four orders of infrared lu...
