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…
Stellar labels for hot stars from low-resolution spectra - I. the HotPayne method and results for 330,000 stars from LAMOST DR6
Maosheng Xiang, Hans-Walter Rix, Yuan-Sen Ting +9
We set out to determine stellar labels from low-resolution survey spectra of hot, OBA stars with effective temperature (Teff) higher than 7500K. This fills a gap in the scientific…
New infrared spectral indices of luminous cold stars: from early K to M-types
Maria Messineo, Donald F. Figer, Rolf-Peter Kudritzki +4
We present infrared spectral indices (1.0-2.3 um) of Galactic late-type giants and red supergiants (RSGs). We used existing and new spectra obtained at resolution power R=2000 with…
The temperatures of red supergiants in low metallicity environments
Gemma González-Torà, Ben Davies, Rolf-Peter Kudritzki +1
The temperatures of red supergiants (RSGs) are expected to depend on metallicity (Z) in such a way that lower-Z RSGs are warmer. In this work, we investigate the Z-dependence of th…
The Araucaria Project. Distances to Nine Galaxies Based on a Statistical Analysis of their Carbon Stars (JAGB Method)
Bartłomiej Zgirski, Grzegorz Pietrzyński, Wolfgang Gieren +13
Our work presents an independent calibration of the J-region Asymptotic Giant Branch (JAGB) method using Infrared Survey Facility (IRSF) photometric data and a custom luminosity fu…
Modified Gravity and the Flux-weighted Gravity-Luminosity Relationship of Blue Supergiant Stars
Eva Sextl, Rolf-Peter Kudritzki, Jochen Weller +2
We calculate models of stellar evolution for very massive stars and include the effects of modified gravity to investigate the influence on the physical properties of blue supergia…
