Now that well over 100 planets have been discovered, we no longer need to ask the question "Are there planets out there?" ... The objective of XO is to find additional hot-Jupiters (like HD 209458b) that transit stars bright enough for detailed follow-up studies to be done with existing telescopes such as HST, Keck, and the VLT. ... Transit observations by themselves provide no information about the mass of the planet and radial velocity studies can yield only minimum masses. ...

... The sky distribution of the BCGs from the HSS sample is shown in Fig. 6 together with BCGs from the SBS and Case surveys (Izotov et al. [ 1993b ]; Pustilnik et al. ... First, we compare the apparent magnitude distributions of the three samples. ... The similar behaviour of the faint end of the apparent magnitude distributions infers that the Northern BCG sample may have a similar completeness down to this limiting magnitude. ...

Next: V652HER AND MERGED BINARY Up: EXTREME HELIUM STARS: PULSATION Previous: MASSES . Although pulsations in EHes appear to be ubiquitous, it is not possible to summarize their properties with a single definition. ... The first discovery of pulsation in an EHe was made by Landolt (1975), who discovered a 0.1day photometric period in V652Her, and by Hill et al. (1981), who measured the radial velocity curve and demonstrated the variations were due to radial pulsation. ... 1987, Jeffery et al. ...

... During the analysis of the surveys carried out on RATAN-600, it was found that almost one fifth of the detected sources shows significant radio flux variations. ... We used the data from "Cold" radio surveys carried out with RATAN-600 in 1980-1994 to search for radio sources with significant flux variability. ...

... This talk will present discoveries of new transiting planets and low mass stars, and the characterisation of their fundamental properties: mass, radius, temperature, and composition. ... The planets discovered by HATSouth orbit a diverse range of host stars, and the candidates identified have a wide range of orbital periods. ... These observations represent some of the highest precision near-infrared time-series photometry performed from the ground, and probe a diverse range of planet atmospheres. ...

William Gilbert . The north-south pointing property of the compass needle was discovered in China around the year 1000, and in 1600 William Gilbert in London showed that this could be explained by the entire Earth being a huge magnet. As a model for the magnetic Earth he used a spherical magnet, which he called "terrella" , the "little Earth." He moved a small compass over the surface of the terrella and demonstrated that it always pointed towards its magnetic poles. ... Magnetic Fields . ...
