The dusty red supergiant progenitor and the local environment of the Type II SN 2023ixf in M101
Ze-Xi Niu, Ning-Chen Sun, Justyn R. Maund +3
As one of the closest supernovae (SNe) in the last decade, SN 2023ixf is an unprecedented target to investigate the progenitor star that exploded. However, there is still significa…
A UV census of the environments of stripped-envelope supernovae
Ning-Chen Sun, Justyn R. Maund, Paul A. Crowther
This paper reports an environmental analysis of 41 uniformly-selected stripped-envelope supernovae (SESNe) based on deep ultraviolet-optical images acquired by the Hubble Space Tel…
An environmental analysis of the Type Ib SN 2019yvr and the possible presence of an inflated binary companion
Ning-Chen Sun, Justyn R. Maund, Paul A. Crowther +5
SN 2019yvr is the second Type Ib supernova (SN) with a possible direct detection of its progenitor (system); however, the spectral energy distribution (SED) of the pre-explosion so…
Toward a better understanding of supernova environments: a study of SNe 2004dg and 2012P in NGC 5806 with HST and MUSE
Ning-Chen Sun, Justyn R. Maund, Paul A. Crowther +2
Core-collapse supernovae (SNe) are the inevitable fate of most massive stars. Since most stars form in groups, SN progenitors can be constrained with information of their environme…
The changing-type SN 2014C may come from an 11- star stripped by binary interaction and violent eruption
Ning-Chen Sun, Justyn R. Maund, Paul A. Crowther
SN 2014C was an unprecedented supernova (SN) that displayed a metamorphosis from Type Ib to Type IIn over 200 days. This transformation is consistent with a helium star havin…
The VMC survey -- XXXVI. Young stellar variability in the Large Magellanic Cloud
Viktor Zivkov, Joana M. Oliveira, Monika G. Petr-Gotzens +11
Studies of young stellar objects (YSOs) in the Galaxy have found that a significant fraction exhibit photometric variability. However, no systematic investigation has been conducte…
Origins of Type Ibn SNe 2006jc/2015G in interacting binaries and implications for pre-SN eruptions
Ning-Chen Sun, Jusytn R. Maund, Ryosuke Hirai +2
Type Ibn supernovae (SNe Ibn) are intriguing stellar explosions whose spectra exhibit narrow helium lines with little hydrogen. They trace the presence of circumstellar material (C…
LEMONY--a Library of Empirical Medium-resolution spectra by Observations with the NAOC Xinglong 2.16\,m and YNAO Gaomeigu 2.4\,m telescopes
Chun Wang, Xiaowei Liu, Yang Huang +15
This study expands the coverage and improves the homogeneity of the distribution of MILES template stars in the parameter space, as well as extends the wavelength coverage of the t…
On the LSP3 estimates of surface gravity for LAMOST-Kepler stars with asteroseismic measurements
Juan-Juan Ren, Xiao-Wei Liu, Mao-Sheng Xiang +13
Asteroseismology allows for deriving precise values of surface gravity of stars. The accurate asteroseismic determinations now available for large number of stars in the Kepler fie…
LAMOST Spectroscopic Survey of the Galactic Anti-centre (LSS-GAC): target selection and the first release of value-added catalogues
Haibo Yuan, Xiaowei Liu, Zhiying Huo +16
As a major component of the LAMOST Galactic surveys, the LAMOST Spectroscopic Survey of the Galactic Anti-centre (LSS-GAC) aims to survey a significant volume of the Galactic thin/…
