The fate of Cyg X-1: an empirical limit on BH-NS merger rate
Cyg X-1:empirical limit BH-NS merger rate
2011/10/12
The recent distance determination allowed precise estimation of the orbital parameters of Cyg X-1, which contains a massive 14.8 Msun BH with a 19.2 Msun O star companion. This system appears to be th...
Spectral and Timing Studies of Cyg X-1 in the Low/Hard State with Suzaku
black hole physics — accretion — stars: individual (Cygnus X-1)—X- ray:binaries
2011/10/11
From 2005 to 2009, 25 observations of Cyg X-1 were performed with Suzaku, achieving a total exposure of 446 ks. In all observations, the source was found in the low/hard state, while the 1.5--12.0 keV...
The Microquasar Cyg X-1: A Short Review
accretion, accretion disks – black hole physics – X-rays:binaries
2011/10/8
We review the spectral properties of the black hole candidate Cygnus X-1. Specifically, we discuss two recent sets of multi-satellite observations. One comprises a 0.5-500 keV spectrum, obtained with ...

Marginally ratio close binary V1191 Cyg
2011/9/27
In this study, we present photometric and spectroscopic variations of the extremely small mass ratio ($q\simeq 0.1$) late-type contact binary system \astrobj{V1191 Cyg}. The parameters for the hot and...

Stars novae – Stars symbiotic stars – Miras
2010/11/10
The nova outburst experienced in 2010 by the symbiotic binary Mira V407 Cyg has been extensively studied at optical and infrared wavelengths with both photometric and spectroscopic observations. This ...
Archival observations from the Very Large Array (VLA) at frequencies between 1.4 GHz and 43
GHz of the 6.6-day O6.5-7+O5.5-6 binary Cyg OB2 #5 over 20 years are re-examined. The aim is to determine t...

Spectral Measurements of Cyg X-3: A Thermal Source Embedded in Hot Plasma within a Cold Shell
Low mass X-ray binaries X-ray sources Cyg X-3
2009/5/19
The attempts at unified model fitting to explain the spectral
variations in Cyg X-3 suggest equally probable fits with a combination of
an absorbed blackbody and a separately absorbed power law with...

2010/9/15
Using measured radial velocity data of five double lined spectroscopic binary systems V380 Cygni, V401 Cyg, V523 Cas, V373 Cas and V2388 Oph, we find corresponding orbital and spectroscopic elements v...

CYG系列斜管(板)除油器（图）
斜管(板)除油器 CYG系列
2008/8/5
斜板除油器依据的基本原理是“浅池理论”，属于物理法除油，是一种重力分离技术。含油污水进入带泪孔的不锈钢波纹聚结板内，就像进入迷宫一般，流动方向以及截面不断改变，使得油滴在浮升过程中相互碰撞聚结，分散的细小油珠合并成大的油珠，大大增大了油珠的上浮速度，从而使污水在斜管组中的向下速度加大，提高了除油设备的效率。而上浮的油珠通过收油槽收集到污油腔，定时排出罐体。分离后的水经集水管进入水腔，通过调节阀自动...
