2015) and evidence for strong-field general relativistic precession has been found in accreting stellarmass BHs via the detection of fast, quasi-periodic oscillations (QPOs Motta et al. 2017) and supermassive black holes (SMBHs) in quasars have been found to display the same stochastic ‘flickering’ variability ( McHardy et al. van der Klis 2000, 2006 Patruno & Watts 2012 Ambrosino et al. 2001) accreting astrophysical systems from young stars and white dwarfs (WDs), to stellar black holes (BHs) in binary systems (e.g. 2014) neutron star (NS) spin periods ranging from milli-seconds to hours have been discovered by observing their X-ray and optical light curves (e.g. For example, the vast majority of all known extra-solar planets have been discovered by searching for transits in the optical light curves of their host stars (e.g. High time-resolution observations have revolutionised our view of the physical processes that take place on short timescales, providing a unique insight into physical phenomena that otherwise would be inaccessible to conventional photometry. As a consequence of these advances, along with the development of new observational techniques, time-domain astronomy has become a strong emerging area in modern astrophysics. Many physical processes occurring on short time scales (of the order of milliseconds to seconds) have only recently been observed thanks to the advent of new technologies, allowing multi-wavelength high-cadence photometric measurements. Las observaciones realizadas con OPTICAM serán de propiedad exclusiva durante seis meses y luego se pondrán a disposición pública para la comunidad astronómica. Dado su diseño instrumental, un amplio rango de fuentes astrofísicas de rápida variabilidad pueden ser observadas con OPTICAM incluyendo estrellas binarias de rayos X, enanas blancas pulsantes, objetos compactos en acrecentamiento, estrellas binarias eclipsantes y exoplanetas. OPTICAM permitirá nominalmente exposiciones en el orden de sub-segundos. OPTICAM estará equipado con tres cámaras sCMOS Andor Zyla 4.2-Plus y un conjunto de filtros SDSS que permitirán cobertura óptica en el rango de 320-1,100 nm. Informamos sobre el desarrollo de un sistema de imagen óptica simultáneo en 3 colores y alta resolución temporal para el telescopio de 2.1 m del Observatorio Astronómico Nacional en San Pedro Mártir, México. Key Words: accretion, accretion discs, instrumentation, photometers, stars, imaging, telescopes. OPTICAM observations will be proprietary for only six months and will then be made publicly available to the astronomical community. Given its instrumental design, a wide range of fast-variability astrophysical sources can be targeted with OPTICAM including X-ray binaries, pulsating white dwarfs, accreting compact objects, eclipsing binaries and exoplanets. OPTICAM will nominally allow sub-second exposures. OPTICAM will be equipped with three 2,048×2,048 pixel Andor Zyla 4.2-Plus sCMOS cameras and a set of SDSS filters allowing optical coverage in the 320-1,100 nm range. We report the development of a high-time resolution, 3-colour, simultaneous optical imaging system for the 2.1 m telescope in the San Pedro Mártir Observatory, México.
