A dynamically discovered and characterized non-accreting neutron star -- M dwarf binary candidate
Tuan Yi, Wei-Min Gu, Zhi-Xiang Zhang +26
Optical time-domain surveys can unveil and characterize exciting but less-explored non-accreting and/or non-beaming neutron stars (NS) in binaries. Here we report the discovery of…
Tomography of the unique on-going jet in the planetary nebula NGC 2392
M. A. Guerrero, S. Cazzoli, J. S. Rechy-Garcia +5
Jets (fast collimated outflows) are claimed to be the main shaping agent of the most asymmetric planetary nebula (PNe) as they impinge on the circumstellar material at late stages…
A Catalog of RV Variable Star Candidates from LAMOST
Zhijia Tian, Xiaowei Liu, Haibo Yuan +14
RV variable stars are important in astrophysics. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has provided ~ 6.5 million stellar spec…
HST STIS UV Spectroscopic Observations of the Protoplanetary Nebula Hen3-1475
Xuan Fang, Ana I. Gomez de Castro, Jesus A. Toala +1
We present UV spectra of the protoplanetary nebula (pPN) Hen3-1475 obtained with the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Telescope (HST). Our deep…
The inside-out planetary nebula around a born-again star
Martin A. Guerrero, Xuan Fang, Marcelo M. Miller Bertolami +8
Planetary nebulae are ionized clouds of gas formed by the hydrogen-rich envelopes of low- and intermediate-mass stars ejected at late evolutionary stages. The strong UV flux from t…
Planetary Nebulae in the Circumnuclear Region of M31: A Spectroscopic Sample
Anqi Li, Zhiyuan Li, Hui Dong +2
Planetary nebulae (PNe) are an important tool for studying the dynamics and chemical evolution of galaxies in the Local Universe, given their characteristic, bright emission line s…
Extended Structures of Planetary Nebulae Detected in H Emission
Xuan Fang, Yong Zhang, Sun Kwok +4
We present narrow-band near-infrared images of a sample of 11 Galactic planetary nebulae (PNe) obtained in the molecular hydrogen (H) 2.122 m and Br 2.166 m emission…
HST STIS observations of the mixing layer in the Cat's Eye Nebula
Xuan Fang, Martin A. Guerrero, Jesus A. Toala +2
Planetary nebulae (PNe) are expected to have a ~10 K interface layer between the 10 K inner hot bubble and the ~10 K optical nebular shell. The PN structure…
Spitzer mid-infrared spectroscopic observations of planetary nebulae
Héctor Mata, Gerardo Ramos-Larios, Martin A. Guerrero +7
We present Spitzer Space Telescope archival mid-infrared (mid-IR) spectroscopy of a sample of eleven planetary nebulae (PNe). The observations, acquired with the Spitzer Infrared S…
