... We present the results of our new observations of TYC 0075 01143 1, a recently discovered double-mode Scuti variable. We improved the frequencies and and pulsation amplitudes, detected the interaction frequencies , , and a possible nonradial frequency . ... The finding chart of TYC 0075 01143 1. ... Using our new observations of TYC 0075 01143 1, we improved the frequencies and , detected oscillations corresponding to interaction between and : and ; we also found a possible nonradial frequency . ...

... 371Gregory Taylor . ... We persent a catalog of 1274 discrete sources detected during a 5 yr, 6 cm, radio-patrol survey of the galactic plane for variavle sources. ... Seventy-five percent of the sources are weaker than 75 mJy, and as a consequence reliable sources and 27 possible variables were detected, of which 64 % exhibited shirt-term variability. ... A comparison with previous centimeter variability studies suggests the possible existence of two distinnct variability components. ...

... CEPHEID VARIABLE STARS: A Cepheid variable or Cepheid is a member of a particular class of very luminous, massive variable stars with pulsation periods of 1-70 days. ... The relationship is calibrated using data collected from Cepheids whose distances are determined by other means. ... Browse through the 68 CCD fits images he sent you, using ds9 and locate the Cepheid variable. ... Image credits: ESA - "http://sci.esa.int/science-e-media/img/20/cepheid-variables.jpg" . ...

... Time delay determinations in astrophysics are used most often to find time delays between flux density variations in different spectral bands and/or lines in AGNs, and different images of gravitationally lensed QSOs. ... OB used an idea to take into account the known gravitational lensing time delay to get combined radio and optical light curves and then to use them for determination of the possible radio-from-optical time delay. ... Correction for change of time delay and radio flux. ...

... A time series analysis is applied to the photometric data obtained by the HST Fine Guidance Sensors (FGS), in order to discover new variable stars and to derive information about microvariability of a large sample of objects. ... Our project is based on a time series analysis of all data sets recorded by the FGSs in order to detect variability among the used Guide Stars. ... Based on ESO 1.5m Danish DFOSC photometry, we have verified variability for three Guide Stars. ...

... Tools . ... Instead, indentation with whitespace characters is used by the interpreter to identify which block a particular line of code belongs to. ... Lastly, the characters used to mark blocks (spaces and tabulators) are invisible (that s why they are usually only used for indentation and as separators), making it particularly hard to identify critical indentation errors and determine the indentation level of a particular line of code (e.g. the first line on a new page of printed Python code). ...

... There are preliminary series of photometric and radio spectral observations of the above-mentioned stars, archival data on the light curves of the stars, results of the search for OH and H 2 O maser emission in IRAS point sources that possess the IR parameters similar to Miras. ... The aim is a detailed study of the maser emission variability. ... In 1996-1997, astronomical observations of Mira Ceti-type stars (miras) were carried out in three spectral ranges: optical, infrared, and radio. ...
