On the Eccentricity Distribution of Exoplanets from Radial Velocity Surveys
We investigate the estimation of orbital parameters by least-χ2 Keplerian fits to radial velocity (RV) data using synthetic data sets. We find that while the fitted period is fairly accurate, the best-fit eccentricity and Mp sin i are systematically biased upward from the true values for low signal-to-noise ratio K/σ . 3 and moderate number of observations Nobs . 60, leading to a suppression of...

طی بررسـی‌های انجام‌شده جهت شناسایی پارازیتوئیدهای لارو شب‌پره‌ی کرم گلوگاه انار،Ectomyelois ceratoniae Zeller (Lep.: Pyralidae)، در باغات انار استان قم، منطقه‌ی قله‌چم واقع در 15 کیلومتری جنوب غربی شهر قم و استان مرکزی، منطقه‌ی ساوه، که در طی سال‌های 86-1385 صورت گرفت، 2 گونه زنبور پارازیتوئید از خانواده‌ی Ichneumonidae از روی لاروهای شب‌پره‌ی فوق جمع‌آوری گردید که برای اولین بار از ایران ...
متن کاملFrom Dense Hot Jupiter to Low Density Neptune: The Discovery of WASP-127b, WASP-136b and WASP-138b
We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18MJ and radius 1.35RJ. This is one of the least massive planets discovered by the WASP project. It orbits a bright host star (Vmag = 10.16) of spectral type G5 with a period of 4.17 days. WASP-127b is a low density planet which has an extended atmosphere with a scale h...
متن کاملSPITZER SECONDARY ECLIPSE DEPTHS WITH MULTIPLE INTRAPIXEL SENSITIVITY CORRECTION METHODS OBSERVATIONS OF WASP-13b, WASP-15b, WASP-16b, WASP-62b, AND HAT-P-22b
We measure the 4.5 μm thermal emission of five transiting hot Jupiters, WASP-13b, WASP-15b, WASP-16b, WASP-62b, and HAT-P-22b using channel 2 of the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. Significant intrapixel sensitivity variations in Spitzer IRAC data require careful correction in order to achieve precision on the order of several hundred parts per million (ppm) for the...
متن کاملWasp stings with multisystem dysfunction.
The insect order of Hymenoptera includes bees, hornets, wasps and fire-ants. Their stings are not usually life threatening, causing mainly local reactions and rarely anaphylaxis. This is a report of an 18 month old child who survived after an unusually severe envenomation, resulting in encephalopathy, hypertension, coagulopathy, intra-vascular hemolysis, hepatic and renal failure, following mul...
