First results of the Kourovka Planet Search: discovery of transiting exoplanet candidates in the first three target fields

We present the first results of our search for transiting exoplanet candidates as part of the Kourovka Planet Search (KPS) project. The primary objective of the project is to search for new hot Jupiters which transit their host stars, mainly in the Galactic plane, in the $R_c$ magnitude range of 11 to 14 mag. Our observations were performed with the telescope of the MASTER robotic network, installed at the Kourovka astronomical observatory of the Ural Federal University (Russia), and the Rowe-Ackermann Schmidt Astrograph, installed at the private Acton Sky Portal Observatory (USA). As test observations, we observed three celestial fields of size $2\times2$ deg$^2$ during the period from 2012 to 2015. As a result, we discovered four transiting exoplanet candidates among the 39000 stars of the input catalogue. In this paper, we provide the description of the project and analyse additional photometric, spectral, and speckle interferometric observations of the discovered transiting exoplanet candidates. Three of the four transiting exoplanet candidates are most likely astrophysical false positives, while the nature of the fourth (most promising) candidate remains to be ascertained. Also, we propose an alternative observing strategy that could increase the project's exoplanet haul.Comment: 11 pages, 16 figures; Accepted for publication in Monthly Notices of the Royal Astronomical Society 201

KPS-1b: The First Transiting Exoplanet Discovered Using an Amateur Astronomer's Wide-field CCD Data

We report the discovery of the transiting hot Jupiter KPS-1b. This exoplanet orbits a V = 13.0 K1-type main sequence star every 1.7 days, has a mass of 1.090 (+0.086 -0.087) MJup and a radius of 1.03 (+0.13 -0.12) RJup. The discovery was made by the prototype Kourovka Planet Search (KPS) project, which used wide-field CCD data gathered by an amateur astronomer using readily available and relatively affordable equipment. Here we describe the equipment and observing technique used for the discovery of KPS-1b, its characterization with spectroscopic observations by the SOPHIE spectrograph and with high-precision photometry obtained with 1m class telescopes. We also outline the KPS project evolution into the Galactic Plane eXoplanet survey. The discovery of KPS-1b represents a new major step of the contribution of amateur astronomers to the burgeoning field of exoplanetology

The male circumcision: the oldest ancient procedure, its past, present and future roles

Circumcision, a surgical removal of male prepuce has existed throughout human history, and it appears it shall exist until humanity ends. During its entire existence, there have been changing reasons or indications from cultural, traditional, religious and currently medical, and it has vehemently been criticized by some individuals for different reasons and in different countries. Emergency of new diseases particularly Human Immunodeficient virus (HIV) has brought the ancient procedure back on spot light, this has come as a result of recent studies which have demonstrated that it does not only reduces significantly the rate of HIV infection, as well as penile cancer and cervical cancer. This has lead to massive male circumcision campaigns in areas with low prevalence of circumcision. On the other hand the socio-cultural and sexual aspects of male circumcision have been studied but often ignored. This article will therefore increase awareness of male circumcision and the increasing roles with time, recommend up scaling of medical male circumcision and possible safe circumcision training to tradition circumcisers
