Discovery and Timing of Millisecond Pulsars in the Globular Cluster M5 (NGC 5904) with FAST and Arecibo
Lei Zhang, Paulo C. C. Freire, Alessandro Ridolfi +29
We report on a comprehensive multi-wavelength study of the pulsars in the globular cluster (GC) M5, including the discovery of M5G, a new compact non-eclipsing "black widow" pulsar…
New evidence of multiple channels for the origin of gamma-ray bursts with extended emission
Q. M. Li, Q. B. Sun, Z. B. Zhang +2
Gamma-ray bursts (GRBs) are the most intense explosions in the universe. GRBs with extended emission (GRB EE) constitute a small subclass of GRBs. GRB EE are divided into EE-I GRBs…
A seven-Earth-radius helium-burning star inside a 20.5-min detached binary
Jie Lin, Chengyuan Wu, Heran Xiong +28
Binary evolution theory predicts that the second common envelope (CE) ejection can produce low-mass (0.32-0.36 Msun) subdwarf B (sdB) stars inside ultrashort-orbital-period binary…
Binary Stars in the New Millennium
Xuefei Chen, Zhengwei Liu, Zhanwen Han
Binary stars are as common as single stars. Binary stars are of immense importance to astrophysicists because that they allow us to determine the masses of the stars independent of…
First Sagittarius A* Event Horizon Telescope Results. VI: Testing the Black Hole Metric
The Event Horizon Telescope Collaboration
Astrophysical black holes are expected to be described by the Kerr metric. This is the only stationary, vacuum, axisymmetric metric, without electromagnetic charge, that satisfies…
First Sagittarius A* Event Horizon Telescope Results. III: Imaging of the Galactic Center Supermassive Black Hole
The Event Horizon Telescope Collaboration
We present the first event-horizon-scale images and spatiotemporal analysis of Sgr A* taken with the Event Horizon Telescope in 2017 April at a wavelength of 1.3 mm. Imaging of Sgr…
First Sagittarius A* Event Horizon Telescope Results. IV. Variability, Morphology, and Black Hole Mass
The Event Horizon Telescope Collaboration
In this paper we quantify the temporal variability and image morphology of the horizon-scale emission from Sgr A*, as observed by the EHT in 2017 April at a wavelength of 1.3 mm. W…
A Phase-resolved View of the Low-frequency Quasiperiodic Oscillations from the Black Hole Binary MAXI J1820+070
Qing C. Shui, S. Zhang, Shuang N. Zhang +21
Although low-frequency quasiperiodic oscillations (LFQPOs) are commonly detected in the X-ray light curves of accreting black hole X-ray binaries, their origin still remains elusiv…
An ALMA Spectroscopic Survey of the Brightest Submillimeter Galaxies in the SCUBA-2-COSMOS Field (AS2COSPEC): Physical Properties of z=2-5 Ultra- and Hyperluminous Infrared Galaxies
Cheng-Lin Liao, Chian-Chou Chen, Wei-Hao Wang +11
We report physical properties of the brightest (-mJy) and not strongly lensed 18 870m selected dusty star-forming galaxies (DSFGs), also known as…
A Shock Flash Breaking Out of a Dusty Red Supergiant
Gaici Li, Maokai Hu, Wenxiong Li +41
Shock breakout emission is light that arises when a shockwave, generated by core-collapse explosion of a massive star, passes through its outer envelope. Hitherto, the earliest det…
Mass Ratio Distribution of Hierarchical Triple Systems from the LAMOST-MRS Survey
Tongyu He, Jiangdan Li, Xuefei Chen +3
Hierarchical triple-star systems consists of three components organised into an inner binary (,) and a more distant outer tertiary () star. The LAMOST Medium-R…
Predicting Astrometric Microlensing Events from Gaia DR3
Jie Su, Jiancheng Wang, Yigong Zhang +2
Currently astrometric microlensing is the only tool that can directly measure the mass of a single star, it can also help us to detect compact objects like isolated neutron stars a…
The Dusty and Extremely Red Progenitor of the Type II Supernova 2023ixf in Messier 101
Danfeng Xiang, Jun Mo, Lingzhi Wang +4
Stars with initial masses in the range of 8-25 solar masses are thought to end their lives as hydrogen-rich supernovae (SNe II). Based on the pre-explosion images of Hubble Space T…
Circumstellar Material Ejected Violently by A Massive Star Immediately before its Death
Jujia Zhang, Han Lin, Xiaofeng Wang +7
Type II supernovae represent the most common stellar explosions in the Universe, for which the final stage evolution of their hydrogen-rich massive progenitors towards core-collaps…
Detection of 12426 SB2 candidates in the LAMOST-MRS, using a binary spectral model
Mikhail Kovalev, Zenghua Zhou, Xuefei Chen +1
We use an updated method for the detection of double-lined spectroscopic binaries (SB2) using values from spectral fits. The method is applied to all spectra from LAMOS…
Spectroscopic triples and a chance alignment. A solution for a problem of suspicious mass ratios for SB2s from Wilson method
Mikhail Kovalev, Xuefei Chen, Zhanwen Han
We selected three double-lined spectroscopic binary systems which have extreme mass ratios, if measured using the Wilson method. We analysed medium resolution spectroscopic observa…
Effect of irradiation on the spin of millisecond pulsars
Shunyi Lan, Xiangcun Meng
A millisecond pulsar (MSP) is an old neutron star (NS) that has accreted material from its companion star, causing it to spin up, which is known as the recycling scenario. During t…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XIII. Ultraviolet Time Lag of H Emission in Mrk 142
V. C. Khatu, S. C. Gallagher, K. Horne +17
We performed a rigorous reverberation-mapping analysis of the broad-line region (BLR) in a highly accreting () active galactic nucleus, Markarian 142 (…
Morphological evidence for nanoflares heating warm loops in the solar corona
