The open cluster NGC 2509. Stellar rotation and main sequence turnoff extension from FLAMES spectroscopy
C. Boeche, J. Alonso-Santiago, A. Bragaglia +8
NGC 2509 is a distant (~2.5 kpc) and little-studied open cluster located in the third Galactic quadrant. It is a moderately old cluster, whose age has not yet been precisely determ…
NGC 1647: A young open cluster with a broad main sequence observed with LAMOST
A. Frasca, M. Qin, J. ALonso-Santiago +4
In this work we present the results of our analysis of medium-resolution LAMOST spectra of candidate members of the cluster NGC 1647 with the aim of determining the stellar paramet…
Precise parameter determination of the open cluster NGC 1647 via asteroseismology of p-mode pulsators
Mingfeng Qin, Jian-Ning Fu, Weikai Zong +4
Asteroseismology of member pulsators provides a robust physical constraint on cluster parameters by linking internal stellar structures to the global properties of the host cluster…
Phase II of the LAMOST-Kepler/K2 Survey. II. Time Domain of Medium-resolution Spectroscopic Observations from 2018 to 2023
Mingfeng Qin, Jian-Ning Fu, Weikai Zong +11
The LAMOST-Kepler/K2 Medium-Resolution Spectroscopic Survey (LK-MRS) conducted time-domain medium-resolution spectroscopic observations of 20 LAMOST plates in the Kepler and K2 fie…
