Kinematics of planetary nebulae in the outskirts of the elliptical galaxy NGC 4697

R. H. Mendez, A. M. Teodorescu, R. -P. Kudritzki +1

We describe the implementation of slitless radial velocity measurements of extragalactic planetary nebulae (PNs) with the 8.2 m Subaru telescope and its Cassegrain imaging spectrog…

The Cepheid Galactic Internet

John G. Learned, R-P. Kudritzki, Sandip Pakvasa +1

We propose that a sufficiently advanced civilization may employ Cepheid variable stars as beacons to transmit all-call information throughout the galaxy and beyond. One can constru…

Observational evidence of CMEs interacting in the inner heliosphere as inferred from MHD simulations

N. Lugaz, W. B. Manchester, I. I. Roussev +1

The interaction of multiple Coronal Mass Ejections (CMEs) has been observed by LASCO coronagraphs and by near-Earth spacecraft, and it is thought to be an important cause of geo-ef…

Observation of a near-threshold enhancement in the e+e- -->Lambda_c+Lambda_c- cross section using initial-state radiation

G. Pakhlova

We report a measurement of the exclusive e+e- -->Lambda_c+ Lambda_c- cross section as a function of center-of-mass energy near the Lambda_c+ Lambda_c- threshold. A clear peak with…

Measurement of single charged pion production in the charged-current interactions of neutrinos in a 1.3 GeV wide band beam

K2K Collaboration, A. Rodriguez, L. Whitehead

Single charged pion production in charged-current muon neutrino interactions with carbon is studied using data collected in the K2K long-baseline neutrino experiment. The mean ener…

A Spectroscopically Unique Main Belt Asteroid: 10537 (1991 RY16)

Nicholas A. Moskovitz, Samuel Lawrence, Robert Jedicke +4

We present visible and near-infrared reflectance spectra and interpreted surface mineralogy for asteroid 10537 (1991 RY16). The spectrum of this object is without precedent amongst…
