H150465: An extraordinarily hot compact star

摘要

The Final Technical Report on H150465: An Extraordinary Hot Compact Star covering the period from 15 Dec. 1990 to 1 Apr. 1992 is presented. The purpose was to support the data analysis of the ROSAT Guest Investigator program to observe H150465, an extremely hot white dwarf star. The observations of H1504 were conducted fortuitously in Jul. 1990, during the PCV (Pre-measurement, Calibration, and Verification) phase of ROSAT observations. Progress during the report period is described.
