The Magellanic Clouds are surrounded by an extended network of gaseous structures. Chief
among these is the Magellanic Stream, an interwoven tail of filaments trailing the Clouds in …

The convective envelopes of solar-type stars and the convective cores of intermediate-and
high-mass stars share boundaries with stable radiative zones. Through a host of processes …

We have derived accurate distances to Galactic globular clusters by combining data from the
Gaia Early Data Release 3 (EDR3) with distances based on Hubble Space Telescope (HST) …

The tip of the red giant branch (TRGB) method provides one of the most accurate and
precise means of measuring the distances to nearby galaxies. Here we present a multi …

In the era of precision cosmology, it is essential to determine the Hubble constant empirically
with an accuracy of one per cent or better. At present, the uncertainty on this constant is …

We report the results of a systematic search for ultra-faint Milky Way satellite galaxies using
data from the Dark Energy Survey (DES) and Pan-STARRS1 (PS1). Together, DES and PS1 …

The variable stars in the VSX catalogue are derived from a multitude of inhomogeneous
data sources and classification tools. This inhomogeneity complicates our understanding of …

We present fits to the broadband photometric spectral energy distributions (SEDs) of 158
eclipsing binaries (EBs) in the Tycho-2 catalog. These EBs were selected because they …

The Cepheid period–luminosity (PL) relation (or Leavitt law) has served as the first rung of
the most widely used extragalactic distance ladder and is central to the determination of the …

We present the most extensive and detailed reddening maps of the Magellanic Clouds
(MCs) derived from the color properties of Red Clump (RC) stars. The analysis is based on …
