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…
On the dynamical evolution of Cepheids in star clusters
František Dinnbier, Richard I. Anderson, Pavel Kroupa
We investigate the occurrence of classical (type-I) Cepheid variable stars (henceforth: Cepheids) in dynamically evolving star clusters from birth to an age of approximately 300 My…
The iron and oxygen content of LMC Classical Cepheids and its implications for the Extragalactic Distance Scale and Hubble constant
Martino Romaniello, Adam Riess, Sara Mancino +6
Classical Cepheids are primary distance indicators and a crucial stepping stone to determining the present-day Hubble constant Ho to the precision and accuracy required to constrai…
Relativistic corrections for measuring Hubble's constant to 1% using stellar standard candles
Richard I. Anderson
Relativistic corrections are estimated for classical Cepheids and the Tip of the Red Giant Branch (TRGB stars), to enable future unbiased 1% measurements of Hubble's constant, $H_0…
Cepheids with giant companions. I. Revealing a numerous population of double-lined binary Cepheids
Bogumił Pilecki, Grzegorz Pietrzyński, Richard I. Anderson +5
Masses of classical Cepheids of 3 to 11 M are predicted by theory but those measured, clump between 3.6 and 5 M. As a result, their mass-luminosity relation is poorly…
