Velocity signal produced by the passage of active regions compared with observations
A calibrated numerical simulation of seasons for which there are observations of the passage of active regions across the visible disk of the sun, generating a...
Venus Atmospheric Zonal Winds from Contemporaneous Akatsuki UVI and IRTF/SpeX 2.3 µm Images
We compare Venus dayside cloud top winds from Akatsuki UVI images to contemporaneous winds in the lower clouds retrieved on the night side using IRTF/SpeX 2.3...
Venus Cloud Tracking Methods and Applications for Akatsuki, IRTF, and Nordic Optical Telescope Images
We present cloud-tracking results from Venus nightside images with velocity errors approaching 1 m/s (rms). The cloud-tracking scheme focuses on 1) reducing the...
Vertical structure of the turbulence above the observatories of the Canary Islands: parameters and statistics for adaptive optics
The statistics of vertical structure of the turbulence affect the complexity of the design and implementation of Multi-Conjugate Adaptive Optics (MCAO) systems...
Vertical Turbulence Profiles at Canary Islands Astronomical Sites
We present the statistical results of the monitoring of the optical turbulence profiles at the Roque de los Muchachos (ORM) and Teide observatories (OT), Spain...
Vertical Velocity Dispersion of the Ionized Gas In NGC 3938
We have studied the kinematics of the ionized gas in the nearly face-on galaxy NGC 3938 by means of observations made with the Fabry-Perot interferometer TAURUS...
