Proplyds in the Flame Nebula NGC 2024
Thomas J. Haworth, Jinyoung S. Kim, Andrew J. Winter +5
A recent survey of the inner pc of the NGC 2024 star forming region revealed two distinct millimetre continuum disc populations that appear to be spatially segregat…
An Improved HR Diagram for the Orion Trapezium Cluster
Min Fang, Jinyoung Serena Kim, Ilaria Pascucci +1
In this paper, we present a study of the Trapezium cluster in Orion. We analyze flux-calibrated VLT/MUSE spectra of 361 stars to simultaneously measure the spectral types, reddenin…
The First Extensive Spectroscopic Study of Young Stars in the North America and Pelican Nebulae Region
Min Fang, Lynne A. Hillenbrand, Jinyoung Serena Kim +5
We present a spectroscopic survey of over 3400 potential members in the North America and Pelican nebulae (NAP) using several low-resolution ( 1300-2000) spectrographs: P…
The origin of a distributed stellar population in the star-forming region W4
Beomdu Lim, Jongsuk Hong, Hyeong-Sik Yun +5
Stellar kinematics provides the key to understanding the formation process and dynamical evolution of stellar systems. Here, we present a kinematic study of the massive star-formin…
Spectral classification of B stars: The empirical sequence using SDSS-IV/APOGEE near-IR data
Valeria G. Ramírez-Preciado, Alexandre Román-Lópes, Carlos G. Román-Zuñiga +5
We present a semi-empirical spectral classification scheme for normal B-type stars using near-infrared spectra (1.5-1.7 m) from the SDSS APOGEE2-N DR14 database. The main motiva…
