Title |
Potential Tests of Gravity with the Triple System | |||||
| Coauthors | ||||||||
|
Abstract |
The millisecond pulsar PSR J1023+0038 is in a hierarchical triple system containing two white dwarfs. The presence of a radio millisecond pulsar in such a complex system allows us to study the system in exquisite detail using pulsar timing. We have already determined nearly all system parameters, and we are working on a test of Einstein's Strong Equivalence Principle. The tremendous density of the pulsar offers the possibility of a test more sensitive than the best current tests by at least an order of magnitude. I will discuss our progress towards such a test and the obstacles that remain. |

Title |
The Best-studied Transitional Pulsar: PSR J1023+0038 | |||||
| Coauthors | ||||||||
|
Abstract |
Three systems have now been observed to transition between radio millisecond pulsar states and accretion-disc states. The first-discovered of these, PSR J1023+0038, is also the best studied. I will summarize the key observational features of this system, including several recent results, and discuss their implications for both accretion physics and the prospect of discovering new transitional systems. |
