Abstract The Clocked Burster, GS 1826-24, is a key source for comparisons of thermonuclear (type-I) burst properties and theoretical predictions. It is the only source which consistently exhibits bright, regular hydrogen-rich bursts, and is thus also a laboratory for studies of rp-process burning. We propose to observe the source twice during AO-4 for 50 ks each to continue our monitoring of the burst behaviour, which commenced in 1997. Measurements of the burst recurrence times, burst profiles and energetics will be compared to the existing dataset and best theoretical predictions to provide an increasingly stringent test of numerical ignition models. With steadily increasing persistent flux (accretion rate) over time, we expect this source to eventually transition to unsteady bursting, providing the opportunity to observe and hence understand this phenomenon better than ever before.

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
