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…
New observations of DW Cnc: where is the 38 min signal?
O. Segura Montero, S. H. Ramirez, J. Echevarria
We present extensive radial-velocity observations of the intermediate polar DW Cnc during its 2018-2019 low state. We show that the 86 min signal, associated with the orbital perio…
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…
From outburst to quiescence: spectroscopic evolution of V1838 Aql imbedded in a bow-shock nebula
J. V. Hernández Santisteban, J. Echevarría, S. Zharikov +15
We analyse new optical spectroscopic, direct-image and X-ray observations of the recently discovered a high proper motion cataclysmic variable V1838 Aql. The data were obtained dur…
Doppler Tomography and Photometry of the Cataclysmic Variable 1RXS J064434.5+334451
J. V. Hernández Santisteban, J. Echevarría, R. Michel +1
We have obtained simultaneous photometric and spectroscopic observations of the cataclysmic variable 1RXS J064434.5+334451. We have calibrated the spectra for slit losses using the…
Photometry of the eclipsing cataclysmic variable SDSS J152419.33+220920.0
R. Michel, J. Echevarria, J. V. Hernandez-Santisteban
Aims. We present new photometry of the faint and poorly studied cataclysmic variable SDSS J152419.33+220920.0, analyze its light curve and provide an accurate ephemeris for this sy…
Astroclimate at San Pedro Mártir I: 2004-2008 Seeing Statistics from the TMT Site Testing Data
L. J. Sánchez, I. Cruz-González, J. Echevarría +6
We present comprehensive seeing statistics for the San Pedro Mártir site derived from the Thirty Meter Telescope site selection data. The observations were obtained between 2004 an…
