Early Near-Infrared Excess and Rapid Disk-Corona Evolution in the Tidal Disruption Event 2024aepd
Yongxin Wu, Yanan Wang, Thomas M. Reynolds +38
We present multi-wavelength observations of the tidal disruption event (TDE) 2024aepd, spanning primarily the first 300 days after discovery. A prominent near-infrared (NIR)…
Bolometric correction factor and radiative efficiency for the super-Eddington accretion flow in tidal disruption events
Yongxin Wu, Erlin Qiao, Xuan Fang +3
The estimate of the bolometric luminosity and the radiative efficiency are two key aspects for understanding the properties of the accretion flow around a supermassive black hole (…
A Morpho-kinematic Study of Galactic High-ADF PNe Based on the VLT/UVES Deep Spectroscopy
Haomiao Huang, Xuan Fang, Jorge Garcia-Rojas +3
We report detailed analyses of deep, high-resolution spectra of three Galactic planetary nebulae (PNe) with high abundance discrepancy factors (ADFs), Hf2-2, M1-42 and NGC6153, obt…
PyEMILI: A New Generation Computer-aided Spectral Line Identifier -- II. Emission-line Identification and Plasma Diagnostics of a Sample of Gaseous Nebulae
Zhijun Tu, Xuan Fang, Jorge García-Rojas +2
In order to test the robustness and reliability of the new generation spectral-line identifier PyEMILI, as initially introduced in Paper I, in line identification and establish a r…
LAMOST Medium-resolution Spectroscopic Survey of the Rosette Nebula
Li-Yue Zhang, Chao-Jian Wu, Xuan Fang +4
We report multi-fiber, medium-resolution spectroscopy of the Rosette Nebula with full spatial coverages, and present a table of the nebular parameters based on the spatially-resolv…
A Massive Yellow Supergiant in the Far Outer Disk of M31: Evidence for In Situ Massive Star Formation Beyond the Optical Radius
Pinjian Chen, Bingqiu Chen, Haibo Yuan +5
While massive stars are known to shape galactic ecosystems, their formation has long been assumed to require the high-density environments of inner galactic disks. This paradigm is…
PyEMILI: A New Generation Computer-aided Spectral Line Identifier
Zhijun Tu, Xuan Fang, Robert Williams +1
Deep high-dispersion spectroscopy of Galactic photoionized gaseous nebulae, mainly planetary nebulae and HII regions, has revealed numerous emission lines. As a key step of spectra…
Periodic Variability of the Central Stars of Planetary Nebulae Surveyed through the Zwicky Transient Facility
Pinjian Chen, Xuan Fang, Xiaodian Chen +1
A consensus has been reached in recent years that binarity plays an important role in the formation and evolution of a significant fraction of planetary nebulae (PNe). Utilizing th…
A Comprehensive Catalog of Emission-line Nebulae, Star Clusters, and Supergiants in M31 from the LAMOST Spectroscopic Survey
Pinjian Chen, Bingqiu Chen, Xuan Fang +5
Spectroscopic observations of various tracers in nearby galaxies, such as Andromeda (M31), play a crucial role in identifying and classifying individual stellar populations and neb…
GTC Spectroscopic Surveys of Planetary Nebulae in the Milky Way and M31
Xuan Fang, Haomiao Huang, Martin A. Guerrero +4
We report spectroscopic surveys of planetary nebulae (PNe) in the Milky Way and Andromeda (M31), using the 10.4-m Gran Telescopio Canarias (GTC). The spectra are of high quality an…
Discovery of a Fast Expanding Shell in the Inside-out Born-Again Planetary Nebula HuBi 1 Through High-Dispersion Integral Field Spectroscopy
J. S. Rechy-García, M. A. Guerrero, E. Santamaría +8
HuBi 1 has been proposed to be member of the rare class of born-again planetary nebulae (PNe), i.e., its central star experienced a very late thermal pulse and ejected highly-proce…
Chemical Abundances of Planetary Nebulae in the Substructures of M31
Xuan Fang, Ruben Garcia-Benito, Martin A. Guerrero +4
We present deep spectroscopy of planetary nebulae (PNe) that are associated with the substructures of the Andromeda Galaxy (M31). The spectra were obtained with the OSIRIS spectrog…
