Hunting for UVdim stars in Galactic Open clusters. Clues from ultraviolet photometry
G. Cordoni, A. P. Milone, L. Casagrande +7
Split main-sequences (MSs) and extended main-sequence turn-offs (eMSTOs) have been observed in nearly all Magellanic Clouds clusters younger than 2 Gyr. More recently, Hubble Space…
C3PO IV: co-natal stars depleted in refractories are magnetically more active -- possible imprints of planets
Jie Yu, Yuan-Sen Ting, Luca Casagrande +14
Chemical abundance anomalies in twin stars have recently been considered tell-tale signs of interactions between stars and planets. While such signals are prevalent, their nature r…
SkyMapper Southern Survey: Data Release 4
Christopher A. Onken, Christian Wolf, Michael S. Bessell +5
We present the fourth data release (DR4) of the SkyMapper Southern Survey (SMSS), the last major step in our hemispheric survey with six optical filters: u, v, g, r, i, z. SMSS DR4…
High-resolution spectroscopic study of extremely metal-poor stars in the Large Magellanic Cloud
W. S. Oh, T. Nordlander, G. S. Da Costa +2
We present detailed abundance results based on UVES high dispersion spectra for 7 very and extremely metal-poor stars in the Large Magellanic Cloud. We confirm that all 7 stars, tw…
The SkyMapper search for extremely metal-poor stars in the Large Magellanic Cloud
W. S. Oh, T. Nordlander, G. S. Da Costa +2
We present results of a search for extremely metal-poor (EMP) stars in the Large Magellanic Cloud, which can provide crucial information about the properties of the first stars as…
Dynamics in the outskirts of four Milky Way globular clusters: it's the tides that dominate
Zhen Wan, Anthony D. Arnold, William H. Oliver +17
We present the results of a spectroscopic survey of the outskirts of 4 globular clusters -- NGC 1261, NGC 4590, NGC 1904, and NGC 1851 -- covering targets within 1 degree from the…
