Discovery of a binary-origin classical Cepheid in a binary system with a 59-day orbital period
Bogumił Pilecki, Ian B. Thompson, Felipe Espinoza-Arancibia +8
We report the discovery of a surprising binary configuration of the double-mode Cepheid OGLE-LMC-CEP-1347 pulsating in the first (P_1=0.690d) and second overtone (P_2=0.556d) modes…
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…
The Milky Way Cepheid Leavitt law based on Gaia DR2 parallaxes of companion stars and host open cluster populations
Louise Breuval, Pierre Kervella, Richard I. Anderson +12
Classical Cepheids provide the foundation for the empirical extragalactic distance ladder. Milky Way Cepheids are the only stars in this class accessible to trigonometric parallax…
Towards precise and accurate Cepheid chemical abundances for 1 $\mbox{H}_0$ measurement: temperature determination
Sara Mancino, Martino Romaniello, Richard I. Anderson +1
One of the outstanding problems in modern physics is the origin is of accelerated expansion of the universe. High-precision determinations of the Hubble parameter $\mbox{H}_0$ at d…
Cepheids under the magnifying glass -- not so simple, after all!
Richard I. Anderson
Classical Cepheids are blue loop stars that have famously been dubbed "magnifying glasses of stellar evolution" and have been studied for a long time. As more and more precise obse…
A stellar relic filament in the Orion star forming region
Tereza Jerabkova, Henri M. J. Boffin, Giacomo Beccari +1
We report the discovery of the oldest stellar substructure in the Orion star forming region (OSFR), the Orion relic filament. The relic filament is physically associated with the O…
