TL;DR: A large survey of over thirty disks using the Gemini Planet Imager (GPI) to see whether the observed dust structures match spectral energy distribution (SED) predictions and have any correlation with stellar properties is presented in this article.
Book ChapterDOI
Accretion and Ejection
TL;DR: The processes by which stars stars accrete their mass are not fully understood as mentioned in this paper, and the origin of this variable accretion is an important outstanding issue in star formation that has not received su cient attention.
Journal ArticleDOI
Characterizing the Stellar Population of NGC 1980
TL;DR: In this paper, the spectral types of the stars in NGC 1980 were determined based on low-resolution spectra, and the age of the population was estimated to be 3 Myr, comparable with the study by Fang et al.
Journal ArticleDOI
Gravitational Focusing and the Star Cluster Initial Mass Function
TL;DR: In this paper, the authors discuss the possibility that gravitational focusing is responsible for the power-law mass function of star clusters N(logM) alpha M-1, and show that such a power law can be produced asymptotically when the mass accretion rate depends upon the mass of the accreting body.
Journal ArticleDOI
Kinematics of the Optically Visible YSOs Toward the Orion B Molecular Cloud
TL;DR: In this article, high-resolution optical spectra of 66 young stars in the Orion B molecular cloud was used to study their kinematics and other properties, including the acceleration of the gas due to stellar feedback.
