A Stable Mineral Fingerprint in the Fading Warm Debris Disk around HD 15407A
Shu Wang, Zhuochao Huang, Xiaodian Chen +2
Extreme debris disks provide time-domain probes of rocky planet assembly after giant impacts. We compare Spitzer and JWST spectra of the warm debris disk around HD 15407A, obtained…
SPHEREx Ultracool Dwarf spectrophotometric Atlas (SUDA): Atmospheric and Fundamental Parameters of Ultracool Dwarfs
Zhijun Tu, Shu Wang, Haomiao Huang +2
The paper presents the SPHEREx Ultracool Dwarf spectrophotometric Atlas (SUDA), a homogeneous dataset of 1675 field ultracool dwarfs with continuous 0.75–5 µm spectra, and derives…
A Search for Variability of Ultracool Dwarfs with the Zwicky Transient Facility
Haomiao Huang, Shu Wang, Xiaodian Chen +2
Rotationally modulated photometric variability of ultracool dwarfs encodes key information about cloud structure and temperature contrasts. Large homogeneous optical datasets are c…
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…
GTC/OSIRIS Deep Spectroscopy of Galactic Compact Planetary Nebulae: PNG048.5+04.2 and PNG068.7+14.8
Haomiao Huang, Xuan Fang, Letizia Stanghellini +5
We report deep long-slit spectroscopy of two Galactic compact planetary nebulae (PNe), PNG048.5+04.2 and PNG068.7+14.8, obtained using the 10.4m Gran Telescopio Canarias (GTC). The…
