Accounting for Convective Blue-Shifts in the Determination of Absolute Stellar Radial Velocities
C. Allende Prieto, L. Koesterke, I. Ramirez +2
For late-type non-active stars, gravitational redshifts and convective blueshifts are the main source of biases in the determination of radial velocities. If ignored, these effects…
Granulation across the HR diagram
I. Ramirez, C. Allende Prieto, D. L. Lambert +2
We have obtained ultra-high quality spectra (R=180,000; S/N>300) with unprecedented wavelength coverage (4400 to 7400 A) for a number of stars covering most of the HR diagram in or…
SW Sextantis stars: the dominant population of CVs with orbital periods between 3-4 hours
P. Rodriguez-Gil, B. T. Gaensicke, H. -J. Hagen +15
[Abridged] We present time-series optical photometry of five new CVs identified by the Hamburg Quasar Survey. The eclipses observed in HS 0129+2933, HS 0220+0603, and HS 0455+8315…
