Rare Occasions: Tidal Disruption Events Rarely Power the AGNs Observed in Dwarf Galaxies

Joanne Tan, Guang Yang, Jonelle L. Walsh +6

Tidal disruption events (TDEs) could be an important growth channel for massive black holes in dwarf galaxies. Theoretical work suggests that the observed active galactic nuclei (A…

How Long Will the Quasar UV/Optical Flickering Be Damped? II. the Observational Test

Guowei Ren, Shuying Zhou, Mouyuan Sun +1

The characteristic timescale at which the variability of active galactic nuclei (AGNs) turns from red noise to white noise can probe the accretion physics around supermassive black…

Nucleosynthesis contribution of neutrino-dominated accretion flows to the solar neighborhood

Yan-Qing Qi, Tong Liu, Mouyuan Sun +1

The elemental abundances of stars reflect the complex enrichment history of the galaxy. To explore and explain the metal enrichment history of the cosmic environment near our solar…

One-off and Repeating Fast Radio Bursts: A Statistical Analysis

Hao-Yan Chen, Wei-Min Gu, Mouyuan Sun +1

According to the number of detected bursts, fast radio bursts (FRBs) can be classified into two categories, i.e., one-off FRBs and repeating ones. We make a statistical comparison…

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…
