Hoyle–Lyttleton Accretion onto Accretion Disks

We investigate Hoyle–Lyttleton accretion for the case where the central source is a luminous accretion disk. In classical Hoyle-Lyttleton accretion onto a “spherical” source, accretion takes place in an axially symmetric manner around a so-called accretion axis. In the spherical case the accretion rate Ṁ is given as ṀHL(1− Γ), where ṀHL is the accretion rate of the classical Hoyle–Lyttleton acc...

A Review of Bondi–Hoyle–Lyttleton Accretion

If a point mass moves through a uniform gas cloud, at what rate does it accrete material? This is the question studied by Bondi, Hoyle and Lyttleton. This paper draws together the work performed in this area since the problem was first studied. Time has shown that, despite the simplifications made, Bondi, Hoyle and Lyttleton made quite accurate predictions for the accretion rate. Bondi–Hoyle–Ly...

Maclyn McCarty (1911–2005)

The editorial board lost a real soul mate when Maclyn McCarty passed away on January 2nd at age 93. While attending the theater with friends, one of the many activities that he enjoyed, he collapsed. “Dr. Mac” was revered worldwide for his remarkable experiments that led to the identification of DNA as the genetic material. This totally unanticipated discovery, and the revolutionary 1944 paper ...
