Extrasolar Carbon Planets
Marc J. Kuchner, S. Seager
We suggest that some extrasolar planets <~ 60 Earth masses will form substantially from silicon carbide and other carbon compounds. Pulsar planets and low-mass white dwarf planets…
Magnetised plasma turbulence in clusters of galaxies
A. A. Schekochihin, S. C. Cowley, R. M. Kulsrud +2
Cluster plasmas are magnetised already at very low magnetic field strength. Low collisionality implies that conservation of the first adiabatic invariant results in an anisotropic…
GBT Observations of Very Low Mass Binary Millisecond Pulsars: A Search for Eclipses
David J. Nice, Ingrid H. Stairs, Zaven Arzoumanian
We searched for eclipses of two millisecond pulsars, PSR J1807-2459 and PSR B1908+00. These pulsars are in very low mass binary systems with orbital parameters similar to those of…
Arecibo Measurements of Pulsar--White Dwarf Binaries: Evidence for Heavy Neutron Stars
David J. Nice, Eric M. Splaver, Ingrid H. Stairs
We summarize constraints on neutron star masses from ongoing timing observations of pulsar-white dwarf binaries at Arecibo. The trend is toward pulsar masses larger than the canoni…
The Power of Exploratory Chandra Observations
S. C. Gallagher, G. T. Richards, W. N. Brandt +1
With its excellent spatial resolution, low background, and hard-band response, the Chandra X-ray Observatory is ideal for performing exploratory surveys. These efficient, sensitive…
The repeating microlensing event OGLE-2003-BLG-095: A plausible case for microlensing of a binary source
Matthew J. Collinge
The apparently repeating microlensing event OGLE-2003-BLG-095 is analyzed. Data were obtained from the OGLE Internet archive and exist in the public domain. The source is relativel…
