A radiometric system developed by the Russian Academy of Sciences' Institute of Applied Astronomy was mounted on the three РТФ-32 radio telescopes constructed as part of the Kvazar project.
The latest version of the planetary part of the numerical ephemerides EPM (Ephemerides of Planets and the Moon) developed at the Institute of Applied Astronomy of the Russian Academy of Sciences is presented.
The Institute of Applied Astronomy of the Russian Academy of Sciences collected more than 25 000 observations for 15 asteroids spanning from 1949 through 1995.
Les photographies directes prises dans le proche infrarouge(λ moyen 0,83 μ)avec un objectif àcourt foyer(F=16 cm)montrent le nuage stellaire“B”découvert,dans la direction du centre galactique,par Kali- niak,Krassovsky et Nikonov,au moyen d'un convertisseur d'images élect- ronique(λ moyen 0,98 u).Le tracédes isophotes,en bleu,en rouge et en infrarouge permet,moyennant certaines hypothèses plausibles,d'évaluer, pour ces trois couleurs,la différence des absorptions interstellaires devant le nuage“B”et devant ...
在银河中心的方向周围,经卡林尼亚克(Kaliniak)、克拉所夫斯基(Krassovsky)和尼可诺夫(Nikonov),用光电像管(Convertisseur d'images électronique)(λ(平均) 0.98μ)所发见的恒星云 B,我们使用短焦距物镜(F=16厘米),在近红外区(λ(平均) 0.83μ)直接拍照,也发见了它.用蓝、红和红外光作等光曲线(isophotes),再加以一些合理的假说,可以计算对于这三个颜色,在 B 云的前面以及在通常照片上可见的人马座的 A 云前面,星际吸光的差异.在 A 云前的吸光率已经大略求出.使用握特-蒲若方斯天文台的施米特望远镜(改正透镜的口径30厘米,焦距59.4厘米),又用81厘米口径的望远镜(焦距488厘米),我们将 B 云完全分解成单颗星.我们在蛇夫座45星东南向附近小区域内,作了照相星等和红外星等的测定.苏联天文学家们以为 A,B 二云和其间的暗区 C 是代表银河中心的密集处,这意见好像被新近发见的蓝光所不能看见的一个球状星团所证实.将星际吸光的效应计入,暂时测定的这星团的距离模数,说明这星团差不多是在银河系的中心.[这工作的完成,...
Ⅱ.The Various Results of the Correction to the Zero Point of the P-L Relation and of the Absolute Magnitude of the RR Lyrae Variables 31 results including 3 results of this paper in connection with the zero point of the period- luminosity relation since Wilson's result of 1939 are tabulated.They are collected in 6 tables according both to the nature of the results and the methods used.A comment for each result is made. Table 1 The Difference,Δ'M_(pg),between the Observed and the Computed Magnitudes (O-C) (T...
On the basis of new facts and laws revealed by modern astronomy and physics, it seems necessary and expedient to introduce the concept of "cos- moscopic" process, to stand side by side with macroscopic and microscopic processes. Cosmoscopic objects differ from macroscopic objects (things seen everday on the Earth as well as meteoric bodies, small asteroids and satellites) in mass and scale just as much as the difference between macroscopic objects and microscopic objects. Gigantic difference in quantity lea...
