Spiral Arms, Infall, and Misalignment of the Circumbinary Disk from the Circumstellar Disks in the Protostellar Binary System L1551 NE [PDF]
, 2017 We report the ALMA Cycle 2 observations of the Class I binary protostellar system L1551 NE in the 0.9 mm continuum, C18O (3–2), 13CO (3–2), SO (78–67), and CS (7–6) emission.

OGLE-LMC-ECL-11893: THE DISCOVERY OF A LONG-PERIOD ECLIPSING BINARY WITH A CIRCUMSTELLAR DISK [PDF]
, 2014 We report the serendipitous discovery of a disk–eclipse system OGLE-LMC-ECL-11893. The eclipse occurs with a period of 468 days, a duration of about 15 days, and a deep (up to ΔmI ≈ 1.5), peculiar, and asymmetric profile.

Effects of stellar flybys on planetary systems: 3D modeling of the circumstellar disk's damping effects [PDF]
, 2014 Stellar flybys in star clusters are suspected to affect the orbital architecture of planetary systems causing eccentricity excitation and orbital misalignment between the planet orbit and the equatorial plane of the star. We explore whether the impulsive

Open Astronomy, 2013 The star V2282 Sgr is positionally consistent with a strong Chandra X-ray and a Spitzer/IRAC mid-infrared source. We derived its long-term I-band light curve from the photographic archives of the Asiago and Catania Observatories, covering the years from ...

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 ...

The Circumstellar Disk of the Butterfly Star in Taurus
, 2003 We present a model of the circumstellar environment of the so-called ``Butterfly Star'' in Taurus (IRAS 04302+2247). The appearance of this young stellar object is dominated by a large circumstellar disk seen edge-on and the light scattering lobes above ...

Are Giant Planets Forming Around HR 4796A? [PDF]
, 2003 We have obtained FUSE and HST STIS spectra of HR 4796A, a nearby 8 Myr old main sequence star that possesses a dusty circumstellar disk whose inclination has been constrained from high resolution near-infrared observations to be ~17 deg from edge-on.

Black Hole Hyperaccretion in Collapsars: A Review
Universe, 2022 The collapsar model is widely accepted as one of the standard scenarios for gamma-ray bursts (GRBs). In the massive collapsar scenario, the core will collapse to a black hole (BH) surrounded by a temporary hyperaccretion disk with a very high accretion ...

A High-mass Protobinary System with Spatially Resolved Circumstellar Accretion Disks and Circumbinary Disk [PDF]
, 2016 High-mass multiples might form via fragmentation of self-gravitational disks or alternative scenarios such as disk-assisted capture. However, only a few observational constraints exist on the architecture and disk structure of high-mass protobinaries and
