Walkaway Star Candidates in IC 348 and Their Possible Birthplaces
The Astrophysical Journal, 2023 Observations and theories reveal that star-forming regions eject their members during the early evolution of the cluster. We present an initial search for stars ejected from the young cluster IC 348 based on an analysis of Gaia EDR3 astrometry of ...

Photometric Determination of the Mass Accretion Rates of Pre-main-sequence Stars. V. Recent Star Formation in the 30 Dor Nebula [PDF]
, 2017 We report on the properties of the low-mass stars that recently formed in the central of 30 Dor, including the R136 cluster. Using the photometric catalog of De Marchi et al., based on observations with the Hubble Space Telescope, and the most recent ...

High-precision Dynamical Masses of Pre-main-sequence Stars with ALMA and Gaia [PDF]
Astrophysical Journal, 2019 The Keplerian rotation in protoplanetary disks can be used to robustly measure stellar masses at very high precision if the source distance is known. We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of spatially and spectrally ...

Pre-main sequence stars in the Lagoon Nebula (M8) [PDF]
, 2006 We report the discovery of new pre-main sequence (PMS) stars in the Lagoon Nebula (M8) at a distance of 1.25 kpc, based on intermediate resolution spectra obtained with the Boller & Chivens spectrograph at the 6.5-m Magellan I telescope (Las Campanas ...

A Study of ISO Spectra for Herbig Ae/Be Stars [PDF]
Journal of Astronomy and Space Sciences, 2002 We present the infrared spectra of Herbig Ae/Be stars including the Infrared Space Observatory (ISO) data. To investigate the overall properties of their circumstellar dust envelope and/or disk, we combine the IR spectra with photometric data ranging ...

Stellar models and isochrones from low-mass to massive stars including pre-main sequence phase with accretion [PDF]
Astronomy & Astrophysics, 2019 Grids of stellar models are useful tools to derive the properties of stellar clusters, in particular young clusters hosting massive stars, and to provide information on the star formation process in various mass ranges.

Revisiting the pre-main-sequence evolution of stars [PDF]
Astronomy & Astrophysics, 2017 Aims. We want to investigate how planet formation is imprinted on stellar surface composition using up-to-date stellar evolution models. Methods. We simulate the evolution of pre-main-sequence stars as a function of the efficiency of heat injection ...

Long-term optical photometric monitoring of the FUor star V900 Mon [PDF]
Serbian Astronomical Journal, 2021 We present results from photometric monitoring of V900 Mon, one of the newly discovered and still under-studied object from the FU Orionis type. The FUor phenomenon is very rarely observed, but it is essential for stellar evolution.
