Noah's Flood and the Associated Tremendous Rainfall as a Possible Result of Collision of a Big Asteroid with the Sun

Y. Y. Shopov, L. T. Tsankov, L. N. Georgiev +4

A good correlation between the growth rate of the cave speleothems and the annual precipitation at the cave site allow quantitative reconstruction of the precipitation. Measuring t…

The Synoptic All-Sky Infrared (SASIR) Survey

Joshua S. Bloom, J. Xavier Prochaska, William Lee +42

We are proposing to conduct a multicolor, synoptic infrared (IR) imaging survey of the Northern sky with a new, dedicated 6.5-meter telescope at San Pedro Mártir (SPM) Observatory.…

The Impact of the Astro2010 Recommendations on Variable Star Science

Lucianne M. Walkowicz, Andrew C. Becker, Scott F. Anderson +13

The next decade of survey astronomy has the potential to transform our knowledge of variable stars. Stellar variability underpins our knowledge of the cosmological distance ladder,…

NLTE Model of NGC 6543's Central Star and its Relation with the Surrounding Planetary Nebula

L. N. Georgiev, M. Peimbert, D. J. Hillier +3

We analyze the chemical composition of the central star of the planetary nebula NGC 6543 based upon a detailed NLTE model of its stellar wind. The logarithmic abundances by number…

Axi-symmetric Models of B[e] Supergiants: I. The Effective Temperature and Mass-loss Dependence of the Hydrogen and Helium Ionization Structure

J. Zsargo, D. J. Hillier, L. N. Georgiev

We calculate the hydrogen and helium ionization in B[e] envelopes and explore their dependence on mass-loss and effective temperature. We also present simulated observations of the…
