Binary populations and stellar dynamics in young clusters

open access: yes, 2008
We first summarize work that has been done on the effects of binaries on theoretical population synthesis of stars and stellar phenomena. Next, we highlight the influence of stellar dynamics in young clusters by discussing a few candidate UFOs ...

Stellar Dynamics around Black Holes in Galactic Nuclei [PDF]

open access: yes, 1998
We classify orbits of stars that are bound to central black holes in galactic nuclei. The stars move under the combined gravitational influences of the black hole and the central star cluster. Within the sphere of influence of the black hole, the orbital

Cooperative Phenomena in Stellar Dynamics [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1962
The dispersion relations for small amplitude waves in systems of gas and stars in relative motion are derived by methods developed for plasma physics, the interstellar gas being treated as a hydrodynamic fluid and the stars as a collisionless gas. The classical Jeans' minimum wavelength for instability in a gas is fundamentally reduced by relative ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Stellar Dynamics of Extreme-Mass-Ratio Inspirals

open access: yes, 2011
Inspiral of compact stellar remnants into massive black holes (MBHs) is accompanied by the emission of gravitational waves at frequencies that are potentially detectable by space-based interferometers. Event rates computed from statistical (Fokker-Planck,

Adiabatic Invariants in Stellar Dynamics: I. Basic concepts [PDF]

open access: yes, 1994
The adiabatic criterion, widely used in astronomical dynamics, is based on the harmonic oscillator. It asserts that the change in action under a slowly varying perturbation is exponentially small.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Continuous stellar mass-loss in N-body models of galaxies [PDF]

open access: yes, 2001
We present an N-body computer code - aimed at studies of galactic dynamics - with a CPU-efficient algorithm for a continuous (i.e. time-dependent) stellar mass-loss. First, we summarize available data on stellar mass-loss and derive the long-term (20 Gyr)
