ABSTRACT
PSR B0950+08 is a 17 Myr old bright radio pulsar at d=260 pc. X-ray observations of this pulsar provide a rare opportunity to test models of polar cap heating by precipitating magnetospheric particles, while the UV-optical observations can test models of internal heating in neutron stars, which are determined by fundamental properties of matter. The only previous XMM-Newton observation was not deep enough to reliably separate the polar cap and magnetospheric components, while optical observations with ground-based telescopes lacked the needed angular resolution. The proposed deep XMM-Newton observations, supplemented by an HST observation, will be the most detailed multiwavelength study of an old radio pulsar to date.

PAPERS
Authors marked in red are (co-)investigators in the proposal

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
