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We present 206 unpublished optical spectra of 104 type II supernovae obtained by the Xinglong 2.16m telescope and Lijiang 2.4m telescope during the period from 2011 to 2018, spanni…
SN 2016ije: An SN 2002es-like Type Ia Supernova Exploded in a Metal-poor and Low-surface Brightness Galaxy
Zhitong Li, Tianmeng Zhang, Xiaofeng Wang +28
We have conducted photometric and spectroscopic observations of the peculiar Type Ia supernova (SN Ia) 2016ije that was discovered through the Tsinghua-NAOC Transient Survey. This…
The environments of Type Ia supernovae with different relative equivalent width of Si II feature in their spectra
Xiang-Cun Meng, Ju-Jia Zhang, Xu-Lin Zhao +2
Although type Ia supernovae are so important in many astrophysical field, e.g. in cosmology, their explosion mechanism and progenitor system are still unclear. In physics, the rela…
The Oxygen Features in Type Ia Supernovae and the Implications for the Nature of Thermonuclear Explosions
Xulin Zhao, Keiichi Maeda, Xiaofeng Wang +6
The absorption feature O I 7773 is an important spectral indicator for type Ia supernovae (SNe~Ia) that can be used to trace the unburned material at outer layers of the exploding…
Optical Observations of the Type Ia Supernova 2011fe in M101 for Nearly 500 Days
Kaicheng Zhang, Xiaofeng Wang, JuJia Zhang +17
We present well-sampled optical observations of the bright Type Ia supernova (SN~Ia) SN 2011fe in M101. Our data, starting from days before maximum light and extending to…
A Luminous Peculiar Type Ia Supernova SN 2011hr: More Like SN 1991T or SN 2007if?
Jujia Zhang, Xiaofeng Wang, Michele Sasdelli +23
Photometric and spectroscopic observations of a slowly declining, luminous Type Ia supernova (SN Ia) SN 2011hr in the starburst galaxy NGC 2691 are presented. SN 2011hr is found to…
The Silicon and Calcium High-Velocity Features in Type Ia Supernovae from Early to Maximum Phases
Xulin Zhao, Xiaofeng Wang, Keiichi Maeda +7
The high-velocity features (HVFs) in optical spectra of type Ia supernovae (SNe Ia) are examined with a large sample including very early-time spectra (e.g., t < -7 days). Multiple…
The THU-NAOC Transient Survey: the Performance and the First-year Result
Tianmeng Zhang, Xiaofeng Wang, Junchen Chen +18
The Tsinghua University-National Astronomical Observatories of China (NAOC) Transient Survey (TNTS) is an automatic survey for a systematic exploration of optical transients (OTs),…
Optical and Ultraviolet Observations of the Narrow-Lined Type Ia SN 2012fr in NGC 1365
JuJia Zhang, XiaoFeng Wang, JinMing Bai +5
Extensive optical and ultraviolet (UV) observations of the type Ia supernova (SN Ia) 2012fr are presented in this paper. It has a relatively high luminosity, with an absolute -b…
Type IIn Supernova SN 2010jl: Optical Observations for Over 500 Days After Explosion
Tianmeng Zhang, Xiaofeng Wang, Chao Wu +16
We present extensive optical observations of a Type IIn supernova (SN) 2010jl for the first 1.5 years after the discovery. The UBVRI light curves demonstrated an interesting two-st…
