Modeling Mid-Infrared Variability of Circumstellar Disks with Non-Axisymmetric Structure
, 2010 Recent mid-infrared observations of young stellar objects have found significant variations possibly indicative of changes in the structure of the circumstellar disk.

Swift/UVOT Photometry of the Planetary Nebula WeBo 1: Unmasking A Faint Hot Companion Star [PDF]
, 2012 We present an analysis of over 150 ks of data on the planetary nebula WeBo 1 (PN G135.6+01.0) obtained with the Swift Ultraviolet Optical Telescope (UVOT). The central object of this nebula has previously been described as a late-type K giant barium star

Mid-infrared interferometry of the massive young stellar object NGC 2264 IRS 1 [PDF]
, 2011 Context. The optically invisible infrared-source NGC 2264 IRS 1 lying north of the Cone Nebula is thought to be a massive young stellar object (∼ 10 M⊙). Although strong infrared excess clearly shows that the central object is surrounded by large amounts

A hot compact dust disk around a massive young stellar object [PDF]
Nature, 2010 Circumstellar disks are an essential ingredient of the formation of low-mass stars. It is unclear, however, whether the accretion-disk paradigm can also account for the formation of stars more massive than about 10 solar masses, in which strong radiation

Interaction of young stellar object jets with their accretion disk
, 2004 I reexamine recent observations of velocity profiles across jets blown by young stellar objects, and argue that the observations do not support the interpretation of jets rotating around their symmetry axes. Instead, I propose that the interaction of the

Studying the Molecular Ambient towards the Young Stellar Object EGO G35.04-0.47 [PDF]
, 2013 We are performing a systematic study of the interstellar medium around extended green objects (EGOs), likely massive young stellar objects driving outflows.

Detection of a large massive circumstellar disk around a high-mass young stellar object in the Carina Nebula [PDF]
, 2011 Context. The characterization of circumstellar disks around young stellar objects can provide important information about the process of star formation and the possible formation of planetary systems. Aims.

Multiple Populations in Low-mass Globular Clusters: Eridanus
The Astrophysical Journal, 2023 Multiple populations (MPs), characterized by variations in light elemental abundances, have been found in stellar clusters in the Milky Way, Magellanic Clouds, as well as several other dwarf galaxies.

A PAN-CARINA YOUNG STELLAR OBJECT CATALOG: INTERMEDIATE-MASS YOUNG STELLAR OBJECTS IN THE CARINA NEBULA IDENTIFIED VIA MID-INFRARED EXCESS EMISSION [PDF]
, 2011 We present a catalog of 1439 young stellar objects (YSOs) spanning the 1.42 deg2 field surveyed by the Chandra Carina Complex Project (CCCP), which includes the major ionizing clusters and the most active sites of ongoing star formation within the Great ...
