The chemical composition of the Orion star forming region
Aims. We re-examine the recombination/collisional emission line (RL/CEL) nebular abundance discrepancy problem in the light of recent high-quality abundance determinations in young stars in the Orion star-forming region. Methods. We re-evaluate the CEL and RL abundances of several elements in the Orion nebula and estimate the associated uncertainties, taking into account the uncertainties in th...
متن کاملParameters for the Eclipsing B - star Binary HD 42401
I present results from an optical spectroscopic investigation of the binary system HD 42401 (V1388 Ori; B2.5 IV-V + B3 V). A combined analysis of V−band photometry and radial velocities indicates that the system has an orbital period of 2.18706 ± 0.00005 days and an inclination of 75.5 ± 0.2 degrees. This solution yields masses and radii of M1 = 7.42 ± 0.08 M⊙ and R1 = 5.60 ± 0.04 R⊙ for the pr...
متن کامل5 Chemical Composition of the Planet - Harboring Star TrES - 1
We present a detailed chemical abundance analysis of the parent star of the transiting extrasolar planet TrES-1. Based on high-resolution Keck/HIRES and HET/HRS spectra, we have determined abundances relative to the Sun for 16 elements (Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Y, and Ba). The resulting average abundance of < [X/H] > = −0.02± 0.06 is in good agreement with initial ...
متن کامل0 v 1 8 D ec 1 99 9 Multiwavelength optical observations of chromospherically active binary system OU Gem
We have analysed several multiwavelength optical observations (Hα, Hβ, Hǫ, Ca ii H & K, Ca ii IRT lines) of chromospherically active binary system OU Gem, taken in three observation runs: March 1996, April 1998 (using the SOFIN spectrograph and the Nordic Optical Telescope) and January 1999 (using the ESA-MUSICOS spectrograph and the Isaac Newton Telescope). The spectra show double Hα and Hβ ab...
متن کاملASTROMETRIC-SPECTROSCOPIC DETERMINATION OF THE ABSOLUTE MASSES OF THE HgMn BINARY STAR φ HERCULIS
The Mercury-Manganese star φ Her is a well known spectroscopic binary that has been the subject of a recent study by Zavala et al. (2006), in which they resolved the companion using long-baseline interferometry. The total mass of the binary is now fairly well established, but the combination of the spectroscopy with the astrometry has not resulted in individual masses consistent with the spectr...
