The dynamical wavelet spectrum of the profile variations reveals large-scale components in the interval 25-50 km/s that move within the -V sin I to V sin i band for the primary star of the system, Aa1 , with a band crossing time of 4h -5h . ...

... We present flux density measurements of the whole sample of 323 galaxies of the HRS in the three bands of the Spectral and Photometric Imaging Receiver (SPIRE), at 250 m, 350 m and 500 m. Aperture photometry is performed on extended galaxies and point spread function (PSF) fitting on timeline data for unresolved objects; we carefully estimate errors and upper limits. ... According to this criterium, in the whole HRS sample, there are 10, 10 and 9 point-like sources at 250, 350 and 500 m,...

НАБЛЮДАЙТЕ КОМЕТУ ХЕЙЛА-БОППА - КОМЕТУ АНОМАЛЬНОЙ ЯРКОСТИ! ... Комету стали активно наблюдать любители на всех континентах земного шара, потому что уже по первым наблюдениям получалось, что комета станет аномально ярким объектом весной 1997 г. На протяжении 1996 г. комета постепенно увеличивала свой блеск - в марте 8-й, в мае 7-й, и в конце августа уже 5-й зв. вел., т. е. стала небесным объектом, хорошо видимым невооруженным глазом. ... Тайна аномальной яркости кометы Хейла-Боппа? ...
