Hidden star-formation in the cluster of galaxies Abell 1689

P. -A. Duc, B. Poggianti, D. Fadda. D. Elbaz +5

At a redshift of 0.18, Abell 1689 is so far the most distant cluster of galaxies for which substantial mid-infrared (MIR) data have been published. We present here the follow-up op…

Kepler's Area Law in the Principia: Filling in some details in Newton's proof of Prop. 1

Michael Nauenberg

During the past 25 years there has been a controversy regarding the adequacy of Newton's proof of Prop. 1 in Book 1 of the {\it Principia}. This proposition is of central importanc…

Determination of masses and other properties of extra-solar planetary systems with more than one planet

Michael Nauenberg

Recent analysis of the Doppler shift oscillations of the light from extra-solar planetary systems indicate that some of these systems have more than one large planet. In this case…

Periodic orbits for three particles with finite angular momentum

Michael Nauenberg

We present a novel numerical method to calculate periodic orbits for dynamical systems by an iterative process which is based directly on the action integral in classical mechanics…

Evolution and Explosion of Very Massive Primordial Stars

A. Heger, S. E. Woosley, I. Baraffe +1

While the modern stellar IMF shows a rapid decline with increasing mass, theoretical investigations suggest that very massive stars (>100 solar masses) may have been abundant in th…

Results on mixing in the D0 system from BaBar

Monika Grothe

With 12.3 fb-1 collected by the BaBar experiment in 2001, the mixing parameter y = Delta(Gamma)/(2 Gamma) is determined from the ratio of the D0 lifetimes measured in the D0 --> K-…

Radial Velocities for 889 Late-type Stars

David L. Nidever, Geoffrey W. Marcy, R. Paul Butler +2

We report radial velocities for 844 FGKM-type main sequence and subgiant stars and 45 K giants, most of which had either low-precision velocity measurements or none at all. These v…

A spanning set for VOA modules

Geoffrey Buhl

We develop a spanning set for weak modules of C_2 co-finite vertex operator algebras. This spanning set has finiteness properties that we use to show weak modules are C_n co-finite…
