The helium common-envelope wind scenario for SN 2020eyj
Xiang-Cun Meng, Philipp Podsiadlowski
SN 2020eyj is the first type Ia supernova (SN Ia) showing the signature of a compact helium-rich circumstellar material (CSM). Such a large CSM is difficult to explain in a single-…
On the surface helium abundance of B-type hot subdwarf stars from the WD+MS channel of Type Ia supernovae
Rui-Jie Ji, Xiang-Cun Meng, Zheng-Wei Liu
The origin of intermediate helium (He)-rich hot subdwarfs are still unclear. Previous studies have suggested that some surviving Type Ia supernovae (SNe Ia) companions from the whi…
Effect of irradiation on the spin of millisecond pulsars
Shunyi Lan, Xiangcun Meng
A millisecond pulsar (MSP) is an old neutron star (NS) that has accreted material from its companion star, causing it to spin up, which is known as the recycling scenario. During t…
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…
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 cooling time of white dwarfs produced from type Ia supernovae
Xiang-Cun Meng, Wu-Ming Yang, Zhong-Mu Li
Type Ia supernovae (SNe Ia) play a key role in measuring cosmological parameters, in which the Phillips relation is adopted. However, the origin of the relation is still unclear. S…
