We consider the spin angular momentum evolution of the accreting components of Algol-type binary stars. In wider Algols the accretion is through a disc so that the accreted material can transfer enough angular momentum to the gainer that material at its equator should be spinning at breakup. We demonstrate that even a small amount of mass transfer, much less than required to produce today’s mass ratios, transfers enough angular momentum to spin the gainer up to this critical rotation velocity… 
Critically-rotating accretors and non-conservative evolution in Algols
Context. During the mass-transfer phase in Algol systems, a large amount of mass and angular momentum are accreted by the gainer star, which can be accelerated up to its critical Keplerian velocity.
On the Modeling of Algol-Type Binaries
In earlier papers, we presented a binary evolutionary code for the purpose of reproducing the orbital parameters, masses, radii, and location in the Hertzsprung Russell diagram (abbreviated as HRD)

Abstract Various processes can lead to non-conservative evolution in binary stars. Under conservative mass transfer, both the total mass and the orbital angular momentum of the system are conserved.
Spin-down of massive rotating stars
Models of rapidly rotating massive stars at low metallicities show significantly different evolution and higher metal yields compared to non-rotating stars. We estimate the spin-down time-scale of
The formation of long-period eccentric binaries with a helium white dwarf
The recent discovery of long-period eccentric binaries hosting a He-white dwarf or a subdwarf star has been challenging binary-star modeling. Based on accurate determinations of the stellar and
Binary evolution using the theory of osculating orbits I. Conservative Algol evolution
Context. Studies of conservative mass transfer in interacting binar y systems widely assume that orbital angular momentum is conserved. However, this only holds under physically unrealistic
Rotation is thought to be a major factor in the evolution of massive stars—especially at low metallicity—with consequences for their chemical yields, ionizing flux, and final fate. Deriving the birth
Evidence for conservative mass transfer in the classical Algol system δ Librae from its surface carbon-to-nitrogen abundance ratio
Algol-type binary systems are the product of rapid mass transfer between the initially more massive component to its companion. It is still unknown whether the process is conservative, or whether
Orbital period decay of compact black hole X-ray binaries: the influence of circumbinary disks?
Recently, compact black hole X-ray binaries XTE J 1118+480 and A0620-00 have been reported to be experiencing a fast orbital period decay, which is two orders of magnitude higher than expected with


Accretion-powered Stellar Winds. III. Spin-Equilibrium Solutions
We compare the stellar wind torque calculated in a previous work (Paper II) to the spin-up and spin-down torques expected to arise from the magnetic interaction between a slowly rotating (~10% of
Accretion-powered Stellar Winds as a Solution to the Stellar Angular Momentum Problem
We compare the angular momentum extracted by a wind from a pre-main-sequence star to the torques arising from the interaction between the star and its Keplerian accretion disk. We find that the wind
Spin-up of Be stars in the pre-main sequence phase
In an attempt to explain faster than average rotation of Be stars, a model for rotational evolution of a pre-main sequence (PMS) star with a weak primordial magnetic field was applied to stars with
Orbital Evolution of Algol Binaries with a Circumbinary Disk
It is generally thought that conservative mass transfer in Algol binaries causes their orbits to be wider, so that the less massive star overflows its Roche lobe. The observed decrease in the orbital
Accretion-powered Stellar Winds. II. Numerical Solutions for Stellar Wind Torques
In order to explain the slow rotation observed in a large fraction of accreting pre-main-sequence stars (CTTSs), we explore the role of stellar winds in torquing down the stars. For this mechanism to
Magnetic braking of T Tauri stars
We construct models for the rotation rates of T Tauri stars whose spin is regulated by magnetic linkage between the star and a surrounding accretion disc. Our models utilise a time-dependent disc
Disk accretion by magnetic neutron stars.
A model for disk accretion by a rotating magnetic neutron star is proposed which includes a detailed description of matter flow in the transition region between the disk and the magnetosphere. It is
Additional measurements of pre-main-sequence stellar rotation
New rotational-velocity measurements for pre-main-sequence stars in the Taurus-Auriga molecular cloud are reported. Rotational velocities or upper limits of 10 km/s are now available for 90 percent
Magnetic fields in massive stars: dynamics and origin
Evidence continues to accumulate in favour of the presence of magnetic fields on the surfaces of massive stars. Some authors hypothesize that such fields originate in a dynamo in the convective core,
Dynamo-generated magnetic fields at the surface of a massive star
Spruit has shown that an astrophysical dynamo can operate in the non-convective material of a differentially rotating star as a result of a particular instability in the magnetic field (the Tayler
