Échelle Spectroscopy of the Chemically Peculiar Star Ori F
Rafael Costero, Christine Allen, Alex Ruelas-Mayorga +4
We analyse Échelle spectra of Ori F obtained by us on six nights unevenly distributed along six years; we identify several hundred spectral lines and measure, for the first t…
New radial velocity observations of AH Her: evidence for material outside the tidal radius
J. Echevarría, J. V. Hernández Santisteban, O. Segura Montero +7
Spectroscopic observations of AH Herculis during a deep quiescent state are put forward. We found the object in a rare long minima, allowing us to derive accurately the semi-amplit…
Simultaneous Generalized and Low-Layer SCIDAR turbulence profiles at San Pedro Mártir Observatory
R. Avila, O. Valdés-Hernández, L. J. Sánchez +4
We present optical turbulence profiles obtained with a Generalized SCIDAR (G-SCIDAR) and a Low Layer SCIDAR (LOLAS) at the Observatorio Astronómico Nacional in San Pedro Mártir (OA…
Extensive Photometry of V1838 Aql during the 2013 Superoutburst
J. Echevarría, E. de Miguel, J. V. Hernández Santisteban +15
We present an in-depth photometric study of the 2013 superoutburst of the recently discovered cataclysmic variable V1838 Aql and subsequent photometry near its quiescent state. A c…
The Dynamical Evolution of Multiple Systems of Trapezium Type
Christine Allen, Alex Ruelas-Mayorga, Leonardo J. Sánchez +1
We have selected archival observational data for several O and B trapezia in the Milky Way. For each of the main components of the trapezia we obtained transverse velocities from t…
On the dynamical evolution of the Orion Trapezium
C. Allen, R. Costero, A. Ruelas-Mayorga +1
We discuss recent observational data on the transverse and radial velocities, as well as on the masses of the main components of the Orion Trapezium. Based on the most reliable val…
