Radial velocity observations of VB10

EPJ Web of Conferences, 2011
VB 10 is the smallest star known to harbor a planet according to the recent astrometric study of Pravdo & Shaklan [1]. Here we present near-infrared (J-band) radial velocity of VB 10 performed from high resolution (R~20,000) spectroscopy (NIRSPEC/KECK II)

EVALUATION OF THE POSSIBILITIES OF PROVIDING THE NECESSARY ACCURACY OF THE RADIAL VELOCITY MEASURING OF A TARGET BY COHERENT-PULSE RADARS OUTSIDE THE LINE OF SIGHT

Сучасні інформаційні системи, 2019
The purpose of the article. The article estimates the possible values of the components of the mean-square error of measuring the radial velocity of the target which appear as a result of fluctuations of the phase of the radio signal outside the radar ...

Measurements of the Reynolds stress in the turbulent premixed flame

Nihon Kikai Gakkai ronbunshu, 2021
It has been shown in our previous study that the bi-modal distribution is seen in the radial component of the gas velocity obtained in the turbulent flame brush, implying that the shear component of the Reynolds stress conditioned on the unburnt mixture ...

Commission 30: Radial Velocities: (Vitesses Radiales) [PDF]

Transactions of the International Astronomical Union, 2000
Commission 30 has 120 members in 28 countries who are active in the area of radial velocities. During the past triennium 11 new members have joined the commission. The work of the commission covers a wide range of topics all of which concern the application of the Doppler effect to astronomical objects, including galaxies and the interstellar medium as

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

, 2012
Aims. We study the Milky Way thin disk with the Radial Velocity Experiment (RAVE) survey. We consider the thin and thick disks as different Galactic components and present a technique to statistically disentangle the two populations.

Relationship between Axial Width and Flow Characteristics of Pump Chamber in Double Volute Centrifugal Pump

Xibei Gongye Daxue Xuebao, 2020
The axial width of pump chamber has a great influence on the flow characteristics of the pump chamber in the centrifugal pump. A single-stage single-suction double volute centrifugal pump with a semi-open impeller was selected as the object.

AESTRA: Deep Learning for Precise Radial Velocity Estimation in the Presence of Stellar Activity

The Astronomical Journal, 2023
Stellar activity interferes with precise radial velocity measurements and limits our ability to detect and characterize planets, in particular Earth-like planets.
