Interstellar absorption lines toward Cep OB4
An analysis of optical echelle spectra towards nine stars in the Cep OB4 association is presented. Interstellar absorption lines which arise in the (1, 0) and (2, 0) bands of the CN A 2Π – X 2Σ+ red system towards BD+66◦ 1661, BD+66◦ 1674, and BD+66◦ 1675 are used to infer accurate CN column densities N(CN). A comparison with earlier measurements in the CN violet system allows to infer a CN Dop...
متن کاملHELIOSPHERIC, ASTROSPHERIC, AND INTERSTELLAR Lya ABSORPTION TOWARD 36 OPHIUCHI1
We use high-resolution UV spectra taken by the Space Telescope Imaging Spectrograph instrument on board the Hubble Space Telescope to study the 5.5 pc line of sight to the K0 V star 36 Oph A. The one interstellar component detected for this line of sight has a velocity inconsistent with the local interstellar cloud (LIC) Ñow vector but consistent with the Ñow vector of the so-called G cloud, a ...
متن کاملCO and H+3 Toward MWC 1080, MWC 349, and LkHα 101
We present high-resolution, near-infrared NIRSPEC observations of the fundamental rovibrational CO and H3 R(1,0), R(1,1), and Q(1,0) transitions toward three early-type young stars: MWC 1080, MWC 349, and LkHα 101. These observations were performed for the purpose of constraining the physical characteristics of the interstellar material along each line of sight. Toward MWC 1080, we detected str...
متن کاملImaging the disk around the luminous young star LkHα 101 with infrared interferometry
The Herbig Ae/Be star LkHα 101 has been imaged at high angular resolution at a number of wavelengths in the near-infrared (from 1 ∼ 3μm) using the Keck 1 Telescope, and also observed in the mid-infrared (11.15 μm) using the U.C. Berkeley Infrared Spatial Interferometer (ISI). The resolved circular disk with a central hole or cavity reported in Tuthill et al. (2001) is confirmed. This is consist...
متن کاملECHELLE SPECTROSCOPY OF INTERSTELLAR ABSORPTION TOWARD k COLUMBAE WITH THE GODDARD HIGH RESOLUTION SPECTROGRAPH
Goddard High Resolution Spectrograph echelle-mode observations of the interstellar absorption lines of Mg II, Si IV, C IV, and N V toward k Columbae (HD 38666) are presented. The observations have a spectral resolution of 3.5 km s~1 and signal-to-noise ratios (S/Ns) of 20È200. The k Col sight line (l\ d \ 0.40 kpc, z\ [0.18 kpc) extends though the Local Bubble and the warm 237¡.3, b \ [27¡.1, n...
