... Authors: Anuradha Koratkar A fundamental component of the Active Galactic Nuclei paradigm is an accretion disk. Yet, the nature of this accretion disk is not well understood. ... Here we discuss the key predictions of this model and summarize all the observational data connected with these predictions. Although the standard disk model is attractive for its theoretical simplicity, many of the key predictions from this model are in disagreement with observations. ... huizinga@stsci.edu . ...

Next: The Orion OB1 Up: Contents Previous: This work . In this chapter, I will define the sample of stars which will be discussed throughout the remainder of the dissertation. I define two coeval sets of PMS stars located in the Orion OB1 association. ... I then describe the X--ray observations which were used to find the PMS stars in this association. After this, I spend several sections detailing the photometric observations and difficulties in placing objects on the H--R diagram. ...

. I joined NAIC staff in December 1992 via NFRA (Netherlands) and IISc/JAP (India). The topics of my current research include: . (1) Search for Neutral hydrogen in the host galaxies of AGNs at different redshifts. (2) Physical nature and spatial distribution of the ionized component of the interstellar matter. (3) Physics of compact extragalactic radio sources. I am a member of the VLBI group and the Friend of VLBI observations at the observatory. 2008 EVN sessions are here. Tapasi Ghosh .

... For GK Hya excess emis­ sion was observed in the Balmer lines and Mg I b lines while TY Pyx showed excess emission in the Balmer lines and Ca II H & K lines. The emission from GK Hya arises from a global phenomenon associated solely with the secondary component. The lack of significant He I D 3 excess absorption and an analy­ sis of the flux ratio in the Balmer lines suggest that the emission originates in prominence­like material seen off the limb of the star. ...
