Investigating non-LTE abundances of Neodymium (Nd) in metal-poor FGK stars
John D. Dixon, Rana Ezzeddine, Yangyang Li +3
The dominant site(s) of the -process are a subject of current debate. Ejecta from -process enrichment events like kilonovae are difficult to directly measure, so we must inst…
Mass, Luminosity, and Stellar Age of Early-type Stars from the LAMOST Survey
Qida Li, Jianping Xiong, Jiao Li +4
Mass () and luminosity () are fundamental parameters of stars but can only be measured indirectly. Typically, effective temperature (), surface gravity (${\rm lo…
The Red Supergiant Progenitor of the Type II Supernova 2024abfl
Jingxiao Luo, Lifu Zhang, Bing-Qiu Chen +9
Linkage between core-collapse supernovae (SNe) and their progenitors is not fully understood and ongoing effort of searching and identifying the progenitors is needed. $\mathrm{SN\…
Estimating the Atmospheric Parameters of Early-type Stars from the Chinese Space Station Telescope (CSST) Slitless Spectra Survey
JiaRui Rao, HaiLiang Chen, JianPing Xiong +6
The measurement of atmospheric parameters is fundamental for scientific research using stellar spectra. The Chinese Space Station Telescope (CSST), scheduled to be launched in 2024…
Periodicity search in the timing of the 25 millisecond pulsars from the second data release of the European Pulsar Timing Array
Iuliana Nitu, Michael Keith, David Champion +17
In this work, we investigated the presence of strictly periodic, as well as quasi-periodic signals, in the timing of the 25 millisecond pulsars from the EPTA DR2 dataset. This is e…
