We present the results of a radial-velocity study of nine new faint SB1 spectroscopic binaries with composite spectra: HD 137975-6, 177984, HDE 226489, 231613-4, 255387-8, 256138-9, 264997-8, 276787 and 293041-2. The observations were made at Haute-P

We present the results of a radial-velocity study of eight Am stars (HD 341, 55822, 61250, 67317, 93991, 162950, 224890 and 225137) observed at Observatoire de Haute-Provence with the CORAVEL instrument. We find that these systems are single-line spe

Spectral Classification of the Hot Components of a Large Sample of Stars with Composite Spectra, and Implication for the Absolute Magnitudes of the Cool Supergiant Components

Autor: N. Ginestet, J.-M. Carquillat

Publikováno v: The Astrophysical Journal Supplement Series. 143:513-537

A sample of 135 stars with composite spectra has been observed in the near-UV spectral region with the Aurelie spectrograph at the Observatoire de Haute-Provence. Using the spectral classifications of the cool components previously determined with ne

Publikováno v: Astronomy & Astrophysics. 390:1027-1032

CQ Lyn is a new double-lined spectroscopic binary, composed of an Am Scuti and a solar-like star, with an orbital period of 12.50736 d and a zero-eccentricity. Physical parameters of both stars are well constrained. The characteristics of the primary

Autor: David Mozurkewich, Arsen R. Hajian, Andrew F. Boden, Christian A. Hummel, Tyler E. Nordgren, N. Ginestet, J.-M. Carquillat, R. F. Griffin

Publikováno v: The Astronomical Journal. 121:1623-1635

We present a three-dimensional solution for the orbit of the double star Omicron Leonis, based on new photoelectric radial velocity data mainly from the Observatoire de Haute-Provence and on interferometric data obtained with the Navy Prototype Optic
