Thick disk kinematics from RAVE and the solar motion [PDF]

, 2012
Radial velocity surveys such as the Radial Velocity Experiment (RAVE) provide us with measurements of hundreds of thousands of nearby stars most of which belong to the Galactic thin, thick disk or halo. Ideally, to study the Galactic disks (both thin and

Ultrafast thin disk lasers: sub-100 fs pulse duration and carrier envelope offset detection

EPJ Web of Conferences, 2013
We present two milestone results that confirm that thin disk lasers are excellent candidates for driving extreme nonlinear optics experiments. In a first experiment using the broadband mixed sesquioxide gain material Yb:LuScO3, we demonstrate that thin ...

The Geneva-Copenhagen Survey of the Solar neighbourhood II. New uvby calibrations and rediscussion of stellar ages, the G dwarf problem, age-metallicity diagram, and heating mechanisms of the disk [PDF]

, 2007
Ages, metallicities, space velocities, and Galactic orbits of stars in the Solar neighbourhood are fundamental observational constraints on models of galactic disk evolution.

The Relative Age of the Thin and Thick Galactic Disks [PDF]

, 2000
We determine the relative ages of the open cluster NGC 188 and selected Hipparcos field stars by isochrone fitting, and compare them to the age of the thick disk globular cluster 47 Tuc. The best fit age for NGC 188 was determined to be $6.5 \pm 1.0$ Gyr.

Formation and Evolution of the Disk System of the Milky Way: [alpha/Fe] Ratios and Kinematics of the SEGUE G-Dwarf Sample

, 2011
We employ measurements of the [alpha/Fe] ratio derived from low-resolution (R~2000) spectra of 17,277 G-type dwarfs from the SEGUE survey to separate them into likely thin- and thick-disk subsamples.

Origin of chemical and dynamical properties of the Galactic thick disk

, 2011
We adopt a scenario in which the Galactic thick disk was formed by minor merging between the first generation of the Galactic thin disk (FGTD) and a dwarf galaxy about 9 Gyr ago and thereby investigate chemical and dynamical properties of the Galactic ...

Magnetohydrodynamic simulations of black hole accretion [PDF]

, 2001
We discuss the results of three-dimensional magnetohydrodynamic simulations, using a pseudo-Newtonian potential, of thin disk (h/r ~ 0.1) accretion onto black holes.

Kinematic and chemical components in the solar neighbourhood

EPJ Web of Conferences, 2012
Abundance data on solar neighbourhood stars suggest the presence of chemically-distinct stellar components in the solar neighbourhood. When the abundances of Fe, α elements, and the r-process element Eu are considered together, stars separate neatly into

Carrier-Envelope Offset Frequency Stabilization of a Thin-Disk Laser Oscillator via Depletion Modulation

IEEE Photonics Journal, 2020
We present a novel concept for the stabilization of the carrier-envelope offset (CEO) frequency of femtosecond pulse trains from thin-disk laser oscillators by exploiting gain depletion modulation in the active gain region.
