Blue supergiants and the zero point of the Tully-Fisher relation: a path to a new independent test of the Hubble constant
Rolf-Peter Kudritzki, Fabio Bresolin, Miguel A. Urbaneka +1
Blue supergiant distances of nearby galaxies obtained with the flux-weighted gravity-luminosity relationship are used for a measurement of the zero points of Tully-Fisher relations…
The Hidden Story of Chemical Evolution in Local Star-Forming Nuclear Rings
Eva Sextl, Rolf-Peter Kudritzki
A VLT/MUSE population synthesis study of metallicities in the nuclear star-forming rings of four disk galaxies (NGC 613, NGC 1097, NGC 3351, NGC 7552) is presented. Disentangling t…
New ultralight scalar particles and the mass-radius relation of white dwarfs -- the important role of Sirius B
Kai Bartnick, Detlev Koester, Rolf-Peter Kudritzki +3
We present the equation of state for two classes of new ultralight particles, a scalar field coupling to electrons and a light QCD axion field coupling to…
Blue supergiants in the Pinwheel Galaxy M101: comparison with H II region chemical abundances, spectroscopic distance and an independent determination of the Hubble constant
Fabio Bresolin, Rolf-Peter Kudritzki, Miguel A. Urbaneja +2
We present a quantitative spectroscopic study of 13 blue supergiant stars in the Pinwheel Galaxy M101, based on data obtained with the Low Resolution Imaging Spectrometer available…
Evolution and star formation history of NGC300 from a chemical evolution model with radial gas inflows
Xiaoyu Kang, Rolf-Peter Kudritzki, Xiaobo Gong +1
In the build-up of galactic discs gas infall is an important ingredient and it produces radial gas inflows as a physical consequence of angular momentum conservation, since the inf…
The TYPHOON Stellar Population Synthesis Survey. II. Pushing Full Spectral Fitting to the Limit in the Nearby Grand Design Barred Spiral M83
Eva Sextl, Rolf-Peter Kudritzki, Fabio Bresolin +7
We apply population synthesis techniques to analyze TYPHOON long slit spectra of the starburst barred spiral galaxy M83. The analysis covers a central square of 5 arcmin side lengt…
