The DA + dMe eclipsing binary EC 13471 – 1258 : its cup runneth over . . . just ⋆
The optical spectrum and light curve of EC13471–1258 shows that it is an eclipsing binary with an orbital period of 3 37 comprising a DA white dwarf and a dMe dwarf. Total eclipses of the white dwarf are observed lasting 14 min, with the partial phases lasting 54 s. On one occasion, two pre-eclipse dips were seen. Timings of the eclipses over ten years show jitter of up to 12 s. Flares from the...
متن کاملDoes the Honey Bee "Risk Cup" Runneth Over? Estimating Aggregate Exposures for Assessing Pesticide Risks to Honey Bees in Agroecosystems.
Honey bees (Apis mellifera) are uniquely vulnerable to nontarget pesticide impacts because, as ubiquitous managed pollinators, they are deliberately transported into areas where crops are grown with pesticides. Moreover, attributes making them excellent managed pollinators, including large long-lived colonies and complex behavior, also make them challenging subjects for toxicity bioassays. For ...
