Clustering Properties of Intermediate and High-mass Young Stellar Objects

The Astronomical Journal, 2023
We have selected 337 intermediate- and high-mass young stellar objects (YSOs; 1.5–20 M _⊙ ) well-characterized with spectroscopy. By means of the clustering algorithm HDBSCAN, we study their clustering and association properties in the Gaia DR3 catalog ...

A systematic survey for eruptive young stellar objects using mid-infrared photometry [PDF]

, 2013
Accretion in young stellar objects (YSOs) is at least partially episodic, i.e. periods with high accretion rates ('bursts') are interspersed by quiescent phases. These bursts manifest themselves as eruptive variability. Here we presenta systematic survey

Embedded Young Stellar Objects near H72.97-69.39: A Forming Super Star Cluster in N79

The Astrophysical Journal
We present 102 embedded young stellar object (YSO) candidates associated with the H72.97-69.39 super star cluster (SSC) in the Large Magellanic Cloud (LMC).

THE PALOMAR TRANSIENT FACTORY ORION PROJECT: ECLIPSING BINARIES AND YOUNG STELLAR OBJECTS

, 2011
The Palomar Transient Factory (PTF) Orion project is one of the experiments within the broader PTF survey, a systematic automated exploration of the sky for optical transients.

Linking the morphology of young stellar objects to their evolutionary stages with self-organizing maps

Astronomy & Astrophysics
Context. Many studies in the past few decades have investigated the evolution of young stellar objects based on their spectral energy distribution. This distribution is heavily affected not only by the evolutionary stage, but also by the morphology of ...

Young Stellar Objects in Orion B

, 2017
I will discuss our search for young stellar objects in the northern part of the Orion molecular cloud B, where we identify almost 200 young stellar objects that coincide or are located close to sites of active star formation.

Bolometric temperatures of young stellar objects

The Astrophysical Journal, 1993
We propose the bolometric temperature T bol as a measure of the circumstellar obscuration and evolutionary development of a young stellar object (YSO). T bol is the temperature of a blackbody having the same mean frequency as the observed continuum spectrum.

Signatures of Companion-Disc Interaction in Young Stellar Objects

, 2023
The protoplanetary discs surrounding young stellar objects are the birthplace of exoplanetary systems. Understanding the evolution of these systems is key to unravelling the formation process of our own Solar system.

The Young Massive Stellar Objects of M17

The Astrophysical Journal, 1997
We present a multiwavelength spectroscopic survey that reveals the ionizing cluster of M17 and uncovers a population of young stellar objects (YSOs) of high mass (M similar to 5-20 M.). The masses of the stars have been determined fairly accurately through optical or near-infrared spectral classification.

Circumstellar Structure Properties of Young Stellar Objects: Envelopes, Bipolar Outflows, and Disks [PDF]

, 2009
Physical properties of the three main structures in young stellar objects (YSOs), envelopes, bipolar outflows, and circumstellar disks, have been studied using radio interferometers: the Berkeley-Illinois-Maryland Association (BIMA) array and the ...
