Tropical Cyclone Winds Synthetic Aperture Radar
2015/7/16
This paper describes algorithms used to retrieve high-resolution wind fields in tropical cyclone conditions from synthetic aperture radar (SAR) data acquired at C-band with either co-polarization or c...
Operational Use and Impact of Satellite Remotely Sensed Ocean Surface Vector Winds in the Marine Warning and Forecasting Environment
Operational Use Satellite Remotely Sensed Ocean Surface Vector Winds Marine Warning Forecasting Environment
2015/7/3
In 2002, a National Oceanographic Partnership Program project was initiated with the ambitious objective of maximizing the use of currently and soon-to-be-available satellite ocean surface vector wind...
Metal enrichment of the intergalactic medium at z=3 by galactic winds
galactic winds intergalactic medium
2014/12/26
Studies of quasar absorption lines reveal that the low-density intergalactic medium (IGM) at z ~ 3 is enriched to between 10-3 and 10-2 solar metallicity. This enrichment may have occurred in an early...
This paper discusses a semi-numerical method of investigating
the enrichment of the intergalactic medium by galactic winds. We
find that most galaxies at z ~ > 3 should be driving winds, and that (i...
Non-equilibrium ionization model for stellar cluster winds and its application
NGC 3603 general
2014/12/23
We have developed a self-consistent physical model for superstellar cluster winds based on combining a 1D steady-state adiabatic wind solution and a non-equilibrium ionization calculation. Comparing w...
Evolution of Super Star Cluster Winds with Strong Cooling
Evolution Super Star Cluster Winds Strong Cooling
2011/10/18
We study the evolution of Super Star Cluster (SSC) winds driven by stellar winds and supernova (SN) explosions. Time-dependent rates at which mass and energy are deposited into the cluster volume, as ...
Modelling interaction of relativistic and non-relativistic winds in binary system PSR B1259-63/SS2883 - II. Impact of magnetization and anisotropy of the pulsar wind
HD – shock waves - pulsars: binaries
2011/10/19
In this paper, we present a numerical study of the properties of the flow produced by the collision of a magnetized anisotropic pulsar wind with its environment in binary system. We compare the impact...
Neutral stability height correction for ocean winds
Neutral stability height correction ocean winds Atmospheric and Oceanic Physics
2011/8/3
Abstract: Adjusting ocean wind observations to a standard height, usually 10 m, requires the use of a boundary layer model, and knowledge of the thermodynamical variables. Height adjustment is complic...
Radiation-driven winds of hot luminous stars. XVI. Expanding atmospheres of massive and very massive stars and the evolution of dense stellar clusters
Radiation mechanisms: general – Methods: numerical – Radiative transfer – early Universe – Stars: early-type – mass- loss – stellar winds – very massive stars – stellar evolution
2011/9/27
Context: Starbursts, and particularly their high-mass stars, play an essential role in the evolution of galaxies. The winds of massive stars not only significantly influence their surroundings, but th...
High spatial resolution monitoring of the activity of BA supergiant winds
High spatial resolution the activity BA supergiant winds
2011/1/13
There are currently two optical interferometry recombiners that can provide spectral resolutions better than 10000, AMBER/VLTI operating in the H-K bands, and VEGA/CHARA, recently commissioned, opera...
The rapid rotation (P=0.44 d) of the M dwarf V374Peg (M4) along with its intense magnetic field point toward magneto-centrifugal acceleration of a coronal wind. In this work, we investigate the struct...
The Physics of Disk Winds, Jets,and X-ray Variability in GRS 1915+105
Disk Winds Jets X-ray Variability
2011/1/11
We present new insights about accretion and ejection physics based on joint RXTE/Chandra HETGS studies of rapid X-ray variability in GRS 1915+105. For the first time, with fast phase-resolved spectros...
Strong [O III] and [N II] emission lines in globular clusters from photoionized R Corona Borealis star winds

2011/1/13
The globular cluster X-ray source CXO J033831.8-352604 in NGC 1399 has recently been found to show strong emission lines of [O III] and [N II] in its optical spectrum in addition to ultraluminous X-ra...
Dynamics of the Antarctic and Arctic mesosphere and lower thermosphere – Part 1: Mean winds
