Minute-cadence Observations of the LAMOST Fields with the TMTS: VI. Absolute Physical Parameters of Contact Binaries
Qiqi Xia, Xiaofeng Wang, Kai Li +16
With the development of wide-field surveys, a large amount of data on short-period W UMa contact binaries have been obtained. Continuous and uninterrupted light curves as well as h…
Minute-Cadence Observations of the LAMOST Fields with the TMTS: IV -- Catalog of Cataclysmic Variables from the First 3-yr Survey
Qichun Liu, Jie Lin, Xiaofeng Wang +24
The Tsinghua University--Ma Huateng Telescopes for Survey (TMTS) started to monitor the LAMOST plates in 2020, leading to the discovery of numerous short-period eclipsing binaries,…
Early-Time Observations of SN 2023wrk: A Luminous Type Ia Supernova with Significant Unburned Carbon in the Outer Ejecta
Jialian Liu, Xiaofeng Wang, Cristina Andrade +44
We present extensive photometric and spectroscopic observations of the nearby Type Ia supernova (SN) 2023wrk at a distance of about 40 Mpc. The earliest detection of this SN can be…
Probing the Shock Breakout Signal of SN 2024ggi from the Transformation of Early Flash Spectroscopy
Jujia Zhang, Luc Dessart, Xiaofeng Wang +11
We present early-time, hour-to-day cadence spectroscopy of the nearby type II supernova (SN II) 2024ggi, which was discovered at a phase when the SN shock just emerged from the red…
The first low-mass eclipsing binary within the fully convective zone from TMTS
Cheng Liu, Xiaofeng Wang, Xiaobing Zhang +17
We present a comprehensive photometric and spectroscopic analysis of the short-period (5.32 hours) and low-mass eclipsing binary TMTSJ0803 discovered by Tsinghua-Ma Huateng T…
Minute-Cadence Observations of the LAMOST Fields with the TMTS V. Machine Learning Classification of TMTS Catalogues of Periodic Variable Stars
Fangzhou Guo, Jie Lin, Xiaofeng Wang +17
Periodic variables are always of great scientific interest in astrophysics. Thanks to the rapid advancement of modern large-scale time-domain surveys, the number of reported variab…
Variable white dwarfs in TMTS: Asteroseismological analysis of a ZZ Ceti star, TMTS J17184064+2524314
Jincheng Guo, Yanhui Chen, Yonghui Yang +24
The Tsinghua University-Ma Huateng Telescope for Survey (TMTS) has been constantly monitoring the northern sky since 2020 in search of rapidly variable stars. To find variable whit…
SN 2020udy: A new piece of the homogeneous bright group in the diverse Iax subclass
Mridweeka Singh, Devendra K. Sahu, Barnabas Barna +23
We present optical observations and analysis of a bright type Iax SN~2020udy hosted by NGC 0812. The light curve evolution of SN~2020udy is similar to other bright Iax SNe. Analyti…
A spectral data release for 104 Type II Supernovae from the Tsinghua Supernova Group
Han Lin, Xiaofeng Wang, Jujia Zhang +33
We present 206 unpublished optical spectra of 104 type II supernovae obtained by the Xinglong 2.16m telescope and Lijiang 2.4m telescope during the period from 2011 to 2018, spanni…
