New Periodograms Separating Orbital Radial Velocities and Spectral Shape Variation
Avraham Binnenfeld, Sahar Shahaf, Richard I. Anderson +1
We present new periodograms that are effective in distinguishing Doppler shift from spectral shape variability in astronomical spectra. These periodograms, building upon the concep…
Observational calibration of the projection factor of Cepheids. II. Application to nine Cepheids with HST/FGS parallax measurements
Joanne Breitfelder, Antoine Mérand, Pierre Kervella +4
The distance to pulsating stars is classically estimated using the parallax-of-pulsation (PoP) method, which combines spectroscopic radial velocity measurements and angular diamete…
Observational calibration of the projection factor of Cepheids I. The Type II Cepheid kappa Pavonis
Joanne Breitfelder, Pierre Kervella, Antoine Mérand +5
The distances of pulsating stars, in particular Cepheids, are commonly measured using the parallax of pulsation technique. The different versions of this technique combine measurem…
