Light curve modeling of the nearest neutron star candidate LAMOST J235456.73+335625.9
Qing-bo Han, Mouyuan Sun, Zhi-Xiang Zhang +1
The discovery of heavy radioactive elements (e.g., ) on Earth suggests that supernova explosions may have occurred near our planet within the past million years,…
Compact Object Candidates with K/M-dwarf Companions from LAMOST Low-resolution Survey
Hui-Jun Mu, Wei-Min Gu, Tuan Yi +6
Searching for compact objects (black holes, neutron stars, or white dwarfs) in the Milky Way is essential for understanding the stellar evolution history, the physics of compact ob…
A White Dwarf-Main Sequence Binary Unveiled by Time-Domain Observations from LAMOST and TESS
Ling-Lin Zheng, Wei-Min Gu, Mouyuan Sun +16
We report a single-lined white dwarf-main sequence binary system, LAMOST J172900.17+652952.8, which is discovered by LAMOST's medium resolution time-domain surveys. The radial velo…
A long-period pre-ELM system discovered from LAMOST medium-resolution survey
Zhi-Xiang Zhang, Ling-Lin Zheng, Wei-Min Gu +16
We present LAMOST~J041920.07+072545.4 (hereafter J0419), a close binary consisting of a bloated extremely low mass pre-white dwarf (pre-ELM WD) and a compact object with an orbital…
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…
An Empirical Bayesian Approach to Limb-darkening in Modeling WASP-121b Transit Light Curves
Fan Yang, Richard J. Long, Ji-Feng Liu +6
We present a novel, iterative method using an empirical Bayesian approach for modeling the limb darkened WASP-121b transit from the TESS light curve. Our method is motivated by the…
