Within the Local Universe galaxies can be studied in great detail star by star, and here we
review the results of quantitative studies in nearby dwarf galaxies. The color-magnitude …

The attempt to understand the physics of the structure of stars and their change in time–their
evolution–has been bothering many physicists and astronomers ever since the last century …

Context. In recent years new observations of pre-main sequence stars (pre-MS) with Z≤ Z⊙
have been made available. To take full advantage of the continuously growing amount of …

We present new reddening maps of the Small Magellanic Cloud (SMC) and Large
Magellanic Cloud (LMC) based on the data of the third phase of the Optical Gravitational …

Stars that start their lives with spectral types O and early B are the progenitors of core-
collapse supernovae, long gamma-ray bursts, neutron stars, and black holes. These …

Aiming at providing a firm mean distance estimate to the SMC, and thus to place it within the
internally consistent Local Group distance framework we recently established, we compiled …

In this tutorial paper we summarize how the star formation (SF) history of a galactic region
can be derived from the colour‐magnitude diagram (CMD) of its resolved stars. The …

We present detailed timing and spectral analyses of the transient X-ray pulsar RX J0209. 6−
7427 in the Small Magellanic Cloud during its 2019 giant outburst. With a better known …

In 2019 November, MAXI detected an X-ray outburst from the known Be X-ray binary system
RX J0209. 6− 7427 located in the outer wing of the Small Magellanic Cloud. We followed the …

We present a catalog of star clusters, associations, and related extended objects in the
Small Magellanic Cloud (SMC) and the Magellanic Bridge with 2741 entries, a factor 2 more …
