They were determined as a result of orbit improving on the base of all kinds of optical observations available in the catalog of observations of the Minor Planet Center on March 16, 2014 (radar observations have not been used at this stage). ... As the MPC orbits do not all were improved simultaneously with EMP orbits, only 383866 sets of elements were used for data comparison (for selected sets of elements process of improvement had started with the use of the same observations). ...

7. Modern CCD Observations of Moving Celestial Objects: Algorithms and Software
... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

Top] [Prev] [Next] . The large number of disks surrounding young forming stars as well as the recent detections of massive extra-solar planets suggest that planetary formation commonly occurs. The next challenge is clearly the detection of Earth-like planets. From the ground their detection is likely to remain problematic due to the very low masses and luminosities inferred, whereas space observations enable these detections. ...

10. ASP: A Good Definition of the Word "Planet": Mission Impossible?
... There has been a heated public discussion in the past few years about whether our ninth planet is really deserving of the name. Since Pluto orbits a star, and is much less luminous, it certainly satisfies the definition we have above. The problem is actually not with Pluto, but with a very large number of other bodies in our Solar System which also satisfy this definition, but which are not called planets. Perhaps the most notable of these is Ceres, the largest asteroid. ... Planet . ...

Detecting Long Period Planets with WASP 1 University of Warwick, Gibbet Hill Road, Coventry, CV4 7AL To estimate the number of transiting planets in this period range, planetary occurrence rates from Kepler (Fressin et al, 2013) for varying spectral type & planet type were used. ... Two `stare' fields are currently available from 2011 (330,000 stars) producing a detection rate of 3.0±2.4 planets (Fig 4). ... Since 2011, WASP-N cameras have observed in `Stare' mode, with cadence of ~1-2min. ...

Since the last Kepler catalog was released in February 2012, the number of candidates discovered in the Kepler data has increased by 20 percent and now totals 2,740 potential planets orbiting 2,036 stars. Based on observations conducted May 2009 to March 2011, the most dramatic increases are seen in the number of Earth-sized and super-Earth-sized candidates discovered, which grew by 43 and 21 percent, respectively. ...
