Hubble Space Telescope survey of Magellanic Cloud star clusters. Photometry and astrometry of 113 clusters and early results
A. P. Milone, G. Cordoni, A. F. Marino +29
In the past years, we have undertaken an extensive investigation of LMC and SMC star clusters based on HST data. We present photometry and astrometry of stars in 101 fields observe…
The role of binarity and stellar rotation in the split main sequence of NGC 2422
Chenyu He, Weijia Sun, Chengyuan Li +8
In addition to the extended main-sequence turnoffs widely found in young and intermediate-age (~ 600 Myr-2 Gyr-old) star clusters, some younger clusters even exhibit split main seq…
Double Mode Cepheids from the Zwicky Transient Facility Survey
Vishwangi Shah, Xiaodian Chen, Richard de Grijs
Multi-mode Cepheids pulsate simultaneously in more than one mode of oscillation. They provide an independent means to test stellar models and pulsation theories. They can also be u…
Search for OB associations in {\sl Gaia} early Data Release 3
Alexander A. Chemel, Richard de Grijs, Elena V. Glushkova +1
The distribution of young stars into OB associations has long been in need of updating. High-precision {\sl Gaia} early Data Release 3 astrometry, coupled with modern machine-learn…
Statistics of BY Draconis Chromospheric Variable Stars
Deepak Chahal, Richard de Grijs, Devika Kamath +1
We present an extensive catalogue of BY Draconis (BY Dra)-type variables and their stellar parameters. BY Dra are main-sequence FGKM-type stars. They exhibit inhomogeneous starspot…
The intrinsic reddening of the Magellanic Clouds as traced by background galaxies -- III. The Large Magellanic Cloud
Cameron P. M. Bell, Maria-Rosa L. Cioni, Angus H. Wright +15
We present a map of the total intrinsic reddening across ~90 deg of the Large Magellanic Cloud (LMC) derived using optical (ugriz) and near-infrared (IR; YJKs) spectral energ…
The VMC survey -- XLV. Proper motion of the outer LMC and the impact of the SMC
Thomas Schmidt, Maria-Rosa L. Cioni, Florian Niederhofer +8
The Large Magellanic Cloud (LMC) is the most luminous satellite galaxy of the Milky Way and owing to its companion, the Small Magellanic Cloud (SMC), represents an excellent labora…
