原始语种摘要: Abstract(#br)We present a new observational campaign, Dwarf, aimed at detection of circumbinary extrasolar planets using the timing of the minima of low‐mass eclipsing binaries. The observations will be performed within an extensive network of relatively small to medium‐size telescopes with apertures of ∼20‐200 cm. The starting sample of the objects to be monitored contains (i) low‐mass eclipsing binaries with M and K components, (ii) short‐period binaries with a sdB or sdO component, and (iii) post‐common‐envelope systems containing a WD, which enable to determine minima with high precision. Since the amplitude of the timing signal increases with the orbital period of an invisible third component, the timescale of the project is long, at least 5‐10 years. The paper gives simple formulas...
