Temporal Evolution of Coronagraphic Dynamic Range, and Constraints on Companions to Vega
Sasha Hinkley, Ben R. Oppenheimer, Remi Soummer +8
The major obstacle to the direct detection of companions to nearby stars is the overwhelming brightness of the host star. Current instruments employing the combination of adaptive…
Low Order Aberrations in Band-Limited Lyot Coronagraphs
Anand Sivaramakrishnan, Remi Soummer, Allic V. Sivaramakrishnan +3
We study the way Lyot coronagraphs with unapodized entrance pupils respond to small, low order phase aberrations. This study is applicable to ground-based adaptive optics coronagra…
An Analysis of Fundamental Waffle Mode in Early AEOS Adaptive Optics Images
R. B. Makidon, A. Sivaramakrishnan, M. D. Perrin +4
Adaptive optics (AO) systems have significantly improved astronomical imaging capabilities over the last decade, and are revolutionizing the kinds of science possible with 4-5m cla…
Massive Star Feedback on the IMF
M. Robberto, J. Song, G. Mora Carrillo +3
We have obtained the first measures of the mass accretion rates on stars of the Trapezium Cluster. They appear systematically lower than those of similar stars in the Taurus-Auriga…
Chandra X-ray observations of Young Clusters II. Orion Flanking Fields Data
Solange V. Ramirez, Luisa Rebull, John Stauffer +7
We present results of Chandra observations of two flanking fields (FF) in Orion, outside the Orion Nebula Cluster (ONC). The observations were taken with the ACIS-I camera with an…
HST/WFPC2 Study of the Trapezium Cluster: the Influence of Circumstellar Disks on the Initial Mass Function
M. Robberto, J. Song, G. Mora Carrillo +3
We have performed the first measures of mass accretion rates in the core of the Orion Nebula Cluster. Four adjacent fields centered on the Trapezium stars have been imaged in the U…
