Radial Distributions of Star Formation and Gas-phase Metallicity in Spiral-Elliptical Galaxy Pairs
Cailu Shi, Shuai Feng, Shiyin Shen +3
Using integral field spectroscopy from SDSS-IV MaNGA, we investigate the radial distributions of star formation rate (SFR) and gas-phase metallicity in spiral galaxies that reside…

The identification of new Herbig Ae/Be stars from LAMOST DR7
Jialin Liu, Jiaming Liu, Jiya Yao +5
Herbig Ae/Be stars (HAeBes) are critical tracers of intermediate- and high-mass star formation, yet their census remains incomplete compared to low-mass young stellar objects like…

Massive Acquisition of Ultraviolet Color Excess Information from GALEX and UVOT Bands
Dongliang Yang, Mingxu Sun, Biwei Jiang +4
This study employs stellar parameters from spectroscopic surveys and Zhang et al. based on Gaia XP spectra, along with photometric data from GALEX, UVOT, and Gaia, to obtain extens…
