Instead of the originally proposed two orbits with two WFC3/UVIS filetrs, we propose to observe with a broader WFC3 filter during one orbit, but increase the number of ACS/WFC orbits from one to two. This will allow us to increase the SNR in both bands. 1338329322 ----- Attempting Submission 1 (Thu Feb 20 19:45:14 GMT 2020) ----- Because of bug in an XMM-Newton Phase 2 tool, Bettina Posselt, a CoI of the joint XMM-HST proposal was missed in the CoI list. We corrected this error. External and internal heating in the old pulsar PSR B0950+08 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. We will observe the target in two visits. Visit 1 consists of two orbis in which the pulsar and a possible faint red galaxy nearby will be imaged with the ACS/WFC F775W filter. Visit 2 consists of one orbit in which the pulsar will be imaged in the WFC3/UVIS F475X filter. These two visits will provide the pulsar's fluxes in two spectral bands and the spectral slope of its magnetospheric emission. To mitigate the CTE losses for this faint target, we place the target close to the readouts of the WFC and UVIS detectors. Applying post-flash is not necessary with the long detections and broad filters used.
