Multiple populations in low mass globular clusters: Palomar 13
Baitian Tang, Yue Wang, Ruoyun Huang +7
Since the discovery of chemically peculiar stars in globular clusters in the last century, the study of multiple populations has become increasingly important, given that chemical…
Multiple stellar populations at less evolved stages: detection of chemical variations among main-sequence dwarfs in NGC 1978
Chengyuan Li, Baitian Tang, Antonino P. Milone +4
Multiple stellar populations (MPs) with different chemical compositions are not exclusive features of old GCs (older than 10 Gyr). Indeed, recent studies reveal that younger cluste…
Aluminum Enhanced Metal-Poor Stars buried in the Inner Galaxy
José G. Fernández-Trincado, Timothy C. Beers, Dante Minniti +5
Stars with higher aluminum and nitrogen enrichment are often the key pieces for the chemical makeup of multiple populations in almost all globular clusters (GCs). There is also com…
The enigmatic globular cluster UKS~1 obscured by the bulge: \textit{H}-band discovery of nitrogen-enhanced stars
José G. Fernández-Trincado, Dante Minniti, Timothy C. Beers +13
The presence of nitrogen-enriched stars in globular clusters provides key evidence for multiple stellar populations (MPs), as has been demonstrated with globular cluster spectrosco…
Central velocity dispersion catalog of LAMOST-DR7 galaxies
Nicola R. Napolitano, Giuseppe D'Ago, Crescenzo Tortora +6
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a major facility to carry out spectroscopic surveys for cosmology and galaxy evolution studies. The sevent…
When does the onset of multiple stellar populations in star clusters occur-III: No evidence of significant chemical variations in main-sequence stars of NGC 419
Chengyuan Li, Yue Wang, Baitian Tang +3
Recent studies have revealed that the onset age for the presence of multiple stellar populations (MPs) in star clusters seems to correspond to the disappearance of the extended mai…
Multi-wavelength observations of the BL Lac object Fermi J1544-0649: one year after its awakening
P. H. T. Tam, P. S. Pal, Y. D. Cui +15
We report observations of a transient source \fermi\ from radio to \grs. \fermi\ was discovered by the {\it Fermi-LAT} in May 2017. Follow-up {\it Swift-XRT} observations revealed…
On the Chemical and Kinematic Consistency Between N-rich Metal-poor Field Stars and Enriched Populations in Globular Clusters
Baitian Tang, J. G. Fernandez-Trincado, Chao Liu +5
Interesting chemically peculiar field stars may reflect their stellar evolution history and their possible origin in a different environment from where they are found now, which is…
