SN 2021pfs: A Type Ia Supernova Likely Affected by Progenitor Metallicity, as Revealed by Comparison with Its Twin Counterpart
Abdusamatjan Iskandar, Xiaofeng Wang, Ali Esamdin +15
We present extensive photometric and spectroscopic observations of the normal type Ia supernovae (SNe Ia) 2021pfs, which occurred in the Seyfert 2 galaxy NGC 5427 at a redshift 0.0…
Investigating the electron temperature of [Ar IV] in planetary nebulae using the DESIRED database
J. GarcÃa-Rojas, E. Reyes-RodrÃguez, J. E. Méndez-Delgado +9
(Abridged) We investigate the behaviour of the electron temperature derived from [Ar IV] lines, Te([Ar IV]), in a sample of PNe to characterize the thermal structure of high-excita…
Double-periodic pulsations simultaneously detected in mid-infrared and hard X-ray emissions during an X1.5 flare
Dong Li, Yuyang Ye, Xianyong Bai +1
Quasi-periodic pulsations (QPPs) have been observed in a broad electromagnetic spectrum, encompassing radio, ultraviolet, white light, X-rays, and Gama-rays. Yet, flare-associated…
The Stellar Abundances and Galactic Evolution Survey (SAGES). V. The First Data Release of the DDO51 Band
Qiqian Zhang, Zhou Fan, Gang Zhao +20
We present the first public data release of DDO51 band from the Stellar Abundances and Galactic Evolution Survey (SAGES), based on Nanshan One-meter Wide-field Telescope (NOWT) obs…
Spatial and spectral constraints on resolved mass-loss of the massive Post-RSG star IRAS 17163-3907 and its Fried Egg Nebula
E. Koumpia, A. Cikota, W. -J. de Wit +12
The fate of massive stars during the latest stages of their evolution is highly dependent on their mass-loss rate and geometry. These processes have a significant influence on star…
VLBI astrometry of radio stars to link radio and optical celestial reference frames - II. 11 radio stars
Jingdong Zhang, Bo Zhang, Shuangjing Xu +10
The alignment between the radio-based International Celestial Reference Frame (ICRF) and the optical Gaia Celestial Reference Frame (Gaia-CRF) is critical for multi-waveband astron…
