Jlost in eq 14, the relative mass lost from the system can be estimated Since J eq. 15 may give the total mass ejected from the system Hence the transferred mass from one component to the other easily can be estimated 6 168 Mass Transfer Advanced Topics in Mass Transfer 4 Effects of magnetic fields on the mass loss and mass transfer Now it is generally accepted among the astrophysicists that close binary... systems exhibiting cyclic evolution around a state of marginal contact, in time scales of about 6 × 106 yr, Mass Transfer, and Effects Magnetic Fields on the Mass Transfer in Close Binary System Mass Transfer, and Effects ofof Magnetic Fields on the Mass Transfer in Close Binary System 11 173 without loss of contact, if spin angular momentum of both components are included; 9 × 106 yr, if spin angular... burning hydrogen in its core 1 See the website, http://www.livingreviews.org Mass Transfer, and Effects Magnetic Fields on the Mass Transfer in Close Binary System Mass Transfer, and Effects ofof Magnetic Fields on the Mass Transfer in Close Binary System 3 1 65 Case B: If the orbital period is less than about 100 days, but longer than a few days, the star will fill its Roche lobe during the rapid expansion... during the onset of RLOF and the orbital properties of the resultant binary depend upon the details of the mass transfer Wood (1 950 ) studied period variations of binaries and suggested that mass ejections could be a cause of period change Huang (1963) revised the problem of mass transfer in binary systems, he modified the Jeans(1924-19 25) mode of mass ejection, through suggesting two modes of mass transfer. .. characteristics of (semidetached, Algol- type) binaries is mass transfer due to Roche lobe filling of late secondary component Such mass exchange will spin -up the mass accreting star (most of whose mass is transferred material, by the end of rapid phase of mass transfer) But according to Wilson et al (19 85) this rapid rotation will be damped quickly, as soon as mass transfer is stopped Among semidetached systems... ˙ ˙ ˙ M J Ω a = +2 + J M a Ω (11) Mass Transfer, and Effects Magnetic Fields on the Mass Transfer in Close Binary System Mass Transfer, and Effects ofof Magnetic Fields on the Mass Transfer in Close Binary System if ˙ a a 5 167 is substituted from equation 10 to equation 11 we get, ˙ ˙ ˙ ˙ ˙ J 5M 1Ω 5M 1P = − = + J 3M 3Ω 3M 3P But substitution of ˙ Ω Ω (12) from 10 in to 11 will give ˙ ˙ ˙ J 3M 1a =... Topics in Mass Transfer increased This phenomena can hinder the detachment of the bubbles adhered to the cathode surface, causing a decrease in the rate of mass transfer with increasing percolation velocity For the mesh geometry, a contrary phenomenon is illustrated The Figure 5 (C) and (D) illustrates the same vector representation, but in this case the curved surface promotes increasing the velocity in. ..
