Exploring the optical properties of redback pulsars: The case of J1717+4308A in the globular cluster M92
Jianxing Chen, Greta Ettorre, Cristina Pallanca +13
Binary millisecond pulsars (MSPs) in globular clusters (GCs) are key for binary and stellar evolution studies under extreme conditions. The identification of their optical companio…
Probing Red Giant Interiors with G-Dominated Mixed Modes I: The Cases of KIC 9145955, KIC 9970396, KIC 9882316 and KIC 11968334
Xinyi Zhang, Tanda Li, Jianxing Chen +4
We perform a detailed asteroseismic analysis of four red giants observed by Kepler: KIC 9145955, KIC 9970396, KIC 9882316, and KIC 11968334. Our study is based on individual oscill…
When LAMOST meets Gaia DR3 Exploring the metallicity of open clusters
R. Zhang, Guo-Jian Wang, Yuxi +9
Context. Open clusters (OCs) are valuable probes of stellar population characteristics. Their age and metallicity provide insights into the chemical enrichment history of the Milky…
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…
The "canonical" White Dwarf Cooling Sequence of M5
Jianxing Chen, Francesco R. Ferraro, Maurizio Salaris +5
Recently, a new class of white dwarfs (dubbed ``slowly cooling WDs'') has been identified in two globular clusters (namely M13 and NGC 6752) showing a horizontal branch (HB) morpho…
A young white dwarf orbiting PSR J1835-3259B in the bulge globular cluster NGC 6652
J. Chen, M. Cadelano, C. Pallanca +8
We report on the discovery of the companion star to the millisecond pulsar PSR J1835-3259B in the Galactic globular cluster NGC 6652. Taking advantage of deep photometric archival…
Slowly cooling white dwarfs in NGC 6752
J. Chen, F. R. Ferraro, M. Cadelano +6
Recently, a new class of white dwarfs (``slowly cooling WDs'') has been identified in the globular cluster M13. The cooling time of these stars is increased by stable thermonuclear…
Slowly cooling white dwarfs in M13 from stable hydrogen burning
J. Chen, F. R. Ferraro, M. Cadelano +6
White Dwarfs (WDs) are the final evolutionary product of the vast majority of stars in the Universe. They are electron-degenerate structures characterized by no stable thermonuclea…
A triplet of the only pulsation mode detected in the DAV star G132-12
Wen-Chao Su, Jian-Ning Fu, Jian-Xing Chen +5
Hydrogen atmosphere pulsating white dwarfs, also known as DAV stars, are the most abundant type of pulsating white dwarfs. High-temperature DAV stars exhibit in general a small num…
PSR J1641+3627F: a low-mass He white dwarf orbiting a possible high-mass neutron star in the globular cluster M13
Mario Cadelano, Jianxing Chen, Cristina Pallanca +5
We report on the discovery of the companion star to the millisecond pulsar J1631+3627F in the globular cluster M13. By means of a combination of optical and near-UV high-resolution…
Radial velocity measurements from LAMOST medium-resolution spectroscopic observations: A pointing towards the Kepler field
Nian Liu, Jian-Ning Fu, Weikai Zong +20
Radial velocity is one of key measurements in understanding the fundamental properties of stars, stellar clusters and the Galaxy. A plate of stars in the Kepler field were observed…
