... Planets . ... The planets were found using the HARPS instrument on the 3.6m telescope at ESOтАЩs La Silla Observatory. ... A planet in orbit around a star causes the star to regularly move towards and away from observers on Earth. ... One newly discovered planet, HD 85512 b, is best hope found so far for a habitable exoplanet. ... The HARPS team so far have found that about 40% of stars similar to own Sun have at least one planet smaller than Saturn (which is 95 times more massive than Earth). ...

... Bojan Nikolic web pages (r. 329) . ... This page describes the software and some pointers for using beam cuts through the Moon or Sun for determining the approximate correlation length-scales of errors of a telescope surface. ... At the moment the software can generate a synthetic beam shape at any frequency with a surface errors which are a sum of distributions with Gaussian-spectrum fluctuations. ... Analysis of surface error distributions through Moon (or Sun) beam cuts . ...

... HST Overview . Overview . ... The interferometer consists of a polarizing beam splitter followed by two Koesters prisms. ... The Koesters prisms are constructed of two halves of fused silica joined together along a coated surface which acts as a dielectric beam splitter. ... This division and phase shift gives the Koesters prism its interferometric properties: the beam reflected from one side of the prism interferes constructively or destructively with the beam transmitted from the other side. ...

Please enter the lightcurve file name and period search parameters: . Lightcurve file: . ... Apply the Heliocentric correction and convert all dates to Terrestrial Time (TT)? ... Also, the Heliocentric correction cannot be applied to such lightcurves. ... This period search service is also available at the mirror sites: Mirror 1 , Mirror 2 , Mirror 3 , Mirror 4 . You may download the latest source code distribution and install the period search service at your own web server. ...

... The main direction is discrete complex analysis, additional directions are rational classification of embeddings and classification of circular surfaces. I. Discrete complex analysis. ... One of our past results was application of discrete complex analysis to description of all polygons which can be tiled by squares (with Prasolov, 2010). ... The first planned result is convergence of discrete harmonic functions on general lattices to a harmonic function when the lattice becomes finer and finer. ...

OSLO LT V5.4 Optical Software For Layout And Optimization . Articles | ... Has anyone out there tried to raytrace a telescope design? ... OSLO LT keeps track of the optical path length each ray travels, so it knows the phase relationship of the light as it travels through the telescope. ... Through the use of OSLO LT, I've been able to refine the optical design of the telescope I'm working on. ... www.astronomy.net . About Astronomy Net | ... dbHTML," "AstroGuide," "ASTRONOMY.NET" & "VA.NET" . ...

... We are developing the following problems: a) combine optical and microwave technic to the indication of non-linear surface waves and wave breaking field; b) modelling of microwave propagation in a multiphase air-water interface; c) obtain quantitative dependencies of microwave radiation on geometry and statistics of wave breaking field in ocean surface; d) monitoring of ocean surface states using optical amd microwave airspace data sets. ... Important issue is spray and underwater bubbles. ...

... Recover counts and channel columns. ... Allocate six vectors with Emin&Emax size : Emed = (Emin + Emax)/2 Edelta = (Emin - Emax)/2 Net_Counts = Src_Counts - Bkg_Counts*Src_Exposure_Time/Bkg_Exposure_Time Net_Counts_Err = sqrt(Src_Counts + Bkg_Counts* ((Src_Exposure_Time/Bkg_Exposure_Time)**2)) Bkg_Counts which yet exists Bkg_Counts_Err = sqrt(Bkg_Counts) For Net_Counts and Bkg_Counts do : Rebin Emed, Edelta, Counts, Counts_Err following the specified binning scheme (auto, size). ... Close plot. ...

Intensity of atmospheric motions in the mabl retrieved from ocean surface radar imagery M. Mityagina E-mail: mityag@iki.rssi.ru Abstract. The paper is dedicated to the theory and practice of analysis of radar images of sea surface, obtained under unstable atmospheres. In this case, the sea surface reveals wind field variations in the marine atmospheric boundary layer (MABL) caused by atmospheric convec-tive processes, accompanied by air motions with mainly vertical direction. ...

... Early on, our interest in chirping analysis functions was motivated by a different kind of chirping phenomenon: chirping due to perspective. ... Our interest in radar, however, drew us toward processes that are more accurately analyzed by linear-FM chirplets. ... We have also constructed other chirplet transforms, such as a three-parameter Doppler chirplet representation that models a source producing a sinusoidal wave, while moving along a straight line (e.g. a train whistle). ...

Next: Basic principles of Up: Time Series Analysis Previous: Time Series Analysis . In spite of enormous amounts of existing software and literature on time series analysis (TSA), only comparatively little work has been done concerning those time series which are most often encountered in astronomy, namely unevenly sampled series. Hence, our first reason for yet another TSA package is to provide tools to handle such series. ... A summary of the commands and their syntaxes is listed in Sect. ...

... These trajectories have an initial flight from the Earth to a large distance (of about 1.5 million km), the following passive flight to the Moon's orbit, an approach to the Moon with a decrease of an energy of a particle (spacecraft) selenocentric motion to a negative value and the temporary capture in an elliptic orbit of the Moon's satellite. ... Several trajectories of this type are determined. ... Ivashkin V. V. On optimal trajectories of space flight to the Moon in the Earth--Moon--Sun system. ...
