The Galactic Bulge can uniquely be studied from large samples of individual stars and is
therefore of prime importance for understanding the stellar population structure of bulges in …

Old-aged stellar distance indicators are present in all Galactic structures (halo, bulge, disk)
and in galaxies of all Hubble types and, thus, are immensely powerful tools for …

We update the capabilities of the open-knowledge software instrument Modules for
Experiments in Stellar Astrophysics (MESA). RSP is a new functionality in MESAstar that …

Context. RR Lyrae stars are excellent tracers of the oldest stars (ages≳ 9–10 Gyr) and
standard candles for measuring the distance to stellar systems that are mainly composed of …

This is the second paper of a series devoted to presenting an updated release of the BaSTI
(a Bag of Stellar Tracks and Isochrones) stellar model and isochrone library. Following the …

We study the fraction of stars in and around the δ Scuti instability strip that are pulsating,
using Gaia DR2 parallaxes to derive precise luminosities. We classify a sample of over 15 …

We measure homogeneous distances to M31 and 38 associated stellar systems (− 16.8≤
MV≤− 6.0), using time-series observations of RR Lyrae stars taken as part of the Hubble …

Machine-learned Identification of RR Lyrae Stars from Sparse, Multi-band Data: The PS1
Sample - IOPscience This site uses cookies. By continuing to use this site you agree to our use …

We present results from the analysis of 401 RR Lyrae stars (RRLs) belonging to the field of
the Milky Way (MW). For a fraction of them multiband (V, K s, W 1) photometry, metal …

We have analyzed a sample of 27,258 fundamental-mode RR Lyrae variable stars (type
RRab) detected recently toward the Galactic bulge by the Optical Gravitational Lensing …
