SHARP Images of Young Stellar Objects

Astrophysics and Space Science, 1995
We present high resolution infrared images of the pre-main sequence star V536 Aql and polarization maps of the reflection nebula IRN Cha observed with the SHARP camera on the ESO NTT. Extended structures are observed near V536 Aql. The polarization pattern of IRN Cha is typical of a centrally illuminated source but with a central band of anomalously ...

Oscillations in Young Stellar Objects

International Astronomical Union Colloquium, 2002
AbstractWe report the discovery of periodicities in the light curve of the Herbig Ae star V346 Ori. We interpret these variations as the superposition of at least two signals with periods P1=42±6 min and P2=68±12 min resulting from stellar oscillations.

Disks around young stellar objects

Pramana, 2011
By 1939, when Chandrasekhar’s classic monograph on the theory of Stellar Structure was published, although the need for recent star formation was fully acknowledged, no one had yet recognized an object that could be called a star in the process of being born.

IRAS Colours of Young Stellar Objects

Publications of the Astronomical Society of Australia, 1991
AbstractThe effects of including low quality IRAS flux data in colour-colour diagrams is investigated, with a view to identifying Young Stellar Objects from the IRAS database. Colour criteria to perform this task are derived.

Observations of Young Stellar Objects

1988
After a brief description of the main properties of embedded protostellar sources, I investigate in some detail the hypothesis that CO bipolar flows are pushed by winds emanating from the infrared central sources associated with the molecular outflows.
