A Probable Optical Counterpart for the Isolated Neutron Star RX J1308.6+2127
D. K. Kaplan, S. R. Kulkarni, M. H. van Kerkwijk
Using a very deep observation with HST/STIS, we have searched for an optical counterpart to the nearby radio-quiet isolated neutron star RX J1308.6+2127 (RBS 1223). We have identif…

The Temperature and Cooling Age of the White-Dwarf Companion to the Millisecond Pulsar PSR B1855+09
M. H. van Kerkwijk, J. F. Bell, V. M. Kaspi +1
We report on Keck and {\em Hubble Space Telescope} observations of the binary millisecond pulsar PSR B1855+09. We detect its white-dwarf companion and measure $\mv=25.90\pm0.12$ an…

Optical Observations of the Binary Pulsar System PSR B1718-19: Implications for Tidal Circularization
M. H. van Kerkwijk, V. M. Kaspi, A. R. Klemola +3
We report on Keck and Hubble Space Telescope optical observations of the eclipsing binary pulsar system PSR B1718-19, in the direction of the globular cluster NGC 6342. These revea…
