An Empirical Sample of Spectra of M-type Stars with Homogeneous Atmospheric-parameter Labels

Autor: Bing Du, A-Li Luo, Song Wang, Yinbi Li, Cai-Xia Qu, Xiao Kong, Yan-xin Guo, Yi-han Song, Fang Zuo

Publikováno v: The Astrophysical Journal Supplement Series, Vol 275, Iss 2, p 42 (2024)

The discrepancies between theoretical and observed spectra, and the systematic differences between various spectroscopic parameter estimates, complicate the determination of atmospheric parameters of M-type stars. In this work, we present an empirica

Projected Rotational Velocities for LAMOST Stars with Effective Temperatures Lower than 9000 K

Autor: Fang Zuo, A-Li Luo, Bing Du, Yinbi Li, Hugh R. A. Jones, Yi-han Song, Xiao Kong, Yan-xin Guo

Publikováno v: The Astrophysical Journal Supplement Series, Vol 271, Iss 1, p 4 (2024)

In Data Release 9 of LAMOST, we present measurements of v sin i for a total of 121,698 stars measured using the Medium Resolution Spectrograph (MRS) and 80,108 stars using the Low Resolution Spectrograph (LRS). These values were obtained through a χ

Mass Accretion, Spectral, and Photometric Properties of T Tauri Stars in Taurus Based on TESS and LAMOST

Autor: Chia-Lung Lin, Wing-Huen Ip, Yao Hsiao, Tzu-Heng Chang, Yi-han Song, A-Li Luo

Publikováno v: The Astronomical Journal, Vol 166, Iss 3, p 82 (2023)

We present the analysis of 16 classical T Tauri stars (CTTSs) using LAMOST and TESS data, investigating spectral properties, photometric variations, and mass accretion rates. All 16 stars exhibit emissions in H α lines, from which the average mass a

Robust Electrodes for Flexible Energy Storage Devices Based on Bimetallic Encapsulated Core–Multishell Structures

Autor: Yan‐Fei Li, Shuyang Ye, Yan‐Hong Shi, Jian Lin, Yi‐Han Song, Yang Su, Xing‐Long Wu, Jing‐Ping Zhang, Hai‐Ming Xie, Zhong‐Min Su, Hai‐Zhu Sun, Dwight S. Seferos

Publikováno v: Advanced Science, Vol 8, Iss 14, Pp n/a-n/a (2021)

Abstract Developing flexible electrodes with high active materials loading and excellent mechanical stability is of importance to flexible electronics, yet remains challenging. Herein, robust flexible electrodes with an encapsulated core‐multishell

Analysis of Stellar Spectra from LAMOST DR5 with Generative Spectrum Networks

Autor: Rui, Wang, A-li, Luo, Shuo, Zhang, Wen, Hou, Bing, Du, Yi-Han, Song, Ke-Fei, Wu, Jian-Jun, Chen, Fang, Zuo, Li, Qin, Xiang-Lei, Chen, Yan, Lu

In this study, the fundamental stellar atmospheric parameters (Teff, log g, [Fe/H] and [{\alpha}/Fe]) were derived for low-resolution spectroscopy from LAMOST DR5 with Generative Spectrum Networks (GSN). This follows the same scheme as a normal artif
