Introducing the ASSESS project: Episodic Mass Loss in Evolved Massive Stars -- Key to Understanding the Explosive Early Universe
A. Z. Bonanos, G. Maravelias, M. Yang +6
Episodic mass loss is not understood theoretically, neither accounted for in state-of-the-art models of stellar evolution, which has far-reaching consequences for many areas of ast…
Properties of luminous red supergiant stars in the Magellanic Clouds
S. de Wit, A. Z. Bonanos, F. Tramper +5
There is evidence that some red supergiants (RSGs) experience short lived phases of extreme mass loss, producing copious amounts of dust. These episodic outburst phases help to str…
The Hubble Catalog of Variables (HCV)
A. Z. Bonanos, M. Yang, K. V. Sokolovsky +33
The Hubble Space Telescope (HST) has obtained multi-epoch observations providing the opportunity for a comprehensive variability search aiming to uncover new variables. We have the…
The massive star population of the Virgo Cluster galaxy NGC 4535
Z. T. Spetsieri, A. Z. Bonanos, M. Kourniotis +10
We analyzed the massive star population of the Virgo Cluster galaxy NGC 4535 using archival Hubble Space Telescope Wide Field Planetary Camera 2 images in filters F555W and F814W,…
The Hubble Catalog of Variables
K. Sokolovsky, A. Bonanos, P. Gavras +22
We aim to construct an exceptionally deep (V ~< 27) catalog of variable objects in selected Galactic and extragalactic fields visited multiple times by the Hubble Space Telescope (…
Empirical Determination of Convection Parameters in White Dwarfs I : Whole Earth Telescope Observations of EC14012-1446
J. L. Provencal, M. H. Montgomery, A. Kanaan +55
We report on analysis of 308.3 hrs of high speed photometry targeting the pulsating DA white dwarf EC14012-1446. The data were acquired with the Whole Earth Telescope (WET) during…
