Ultrasonic sound velocity measurement in samples of soft materials through under-resonance excitation
(2005)
Ultrasound (US) velocity determination is a valuable characterization technique, providing important information on elastic properties of materials. Sound velocity can be obtained accurately in the pulsed method if the ...
Rotational velocities for m dwarfs
(2009)
We present spectroscopic rotation velocities (v sin i) for 56 M dwarf stars using high resolution HET HRS red spectroscopy. In addition we have also determined photometric effective temperatures, masses and metallicities ...
The central velocity dispersion of the Milky Way bulge
(2018)
Context. Current spectroscopic and photometric surveys are providing a comprehensive view of the Milky Way bulge stellar population properties with unprecedented accuracy. This in turn allows us to explore the correlation ...
Accurate stellar kinematics at faint magnitudes: Application to the Boötes i dwarf spheroidal galaxy
(2011)
We develop, implement and characterise an enhanced data reduction approach which delivers precise, accurate, radial velocities from moderate resolution spectroscopy with the fibre-fed VLT/FLAMES+GIRAFFE facility. This ...
