Stellar kinematics of barred galaxies
, 1999 I show that the counter-rotating core of the barred galaxy NGC 5728 could be explained by the internal dynamics of the bar. This supports the idea that the nuclear bar is counter-rotating.

Local stellar kinematics from Hipparcos data [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 (shortened) From a kinematically unbiased subsample of the Hipparcos catalogue we have redetermined as a function of colour the kinematics of main-sequence stars. The stars' mean heliocentric velocity nicely follows the asymmetric drift relation, except for stars blueward of B-V=0.1. Extrapolating to zero dispersion yields for the velocity of the Sun w.

Gas and Stellar Kinematics in NGC 6240 [PDF]
Symposium - International Astronomical Union, 2001 We present results from sub-arcsecond near infrared integral field spectroscopy and millimeter IRAM-interferometry of the interacting galaxy NGC 6240. Using stellar absorption features in the NIR we determined the stellar velocity field and dispersion in NGC 6240.

On the origin of the kinematical differences between the stellar halo and the old globular cluster system in the Large Magellanic Cloud [PDF]
, 2007 We discuss structural and kinematical properties of the stellar halo and the old globular cluster system (GCS) in the Large Magellanic Cloud (LMC) based on numerical simulations of the LMC formation.

Modeling gas and stellar kinematics in disc galaxies [PDF]
, 2001 We present V-band surface photometry and major-axis kinematics of stars and ionized gas of three early-type spiral galaxies, namely NGC 772, NGC 3898 and NGC 7782. For each galaxy we built a self-consistent Jeans model for the stellar kinematics, adopting the light distribution of bulge and disc derived by means of a two-dimensional parametric ...

STECKMAP: STEllar Content and Kinematics from high resolution galactic spectra via Maximum A Posteriori [PDF]
, 2005 We introduce STECKMAP (STEllar Content and Kinematics via Maximum A Posteriori), a method to recover the kinematical properties of a galaxy simultaneously with its stellar content from integrated light spectra.

Kinematics and stellar population of NGC 4486A [PDF]
Astronomy & Astrophysics, 2011 NGC 4486A is a low-luminosity elliptical galaxy harbouring an edge-on nuclear disk of stars and dust. It is known to host a super-massive black hole. We study its large-scale kinematics and stellar population along the major axis to investigate the link between the nuclear and global properties.

The Stellar and Gaseous Kinematics in NGC 253 [PDF]
The Astrophysical Journal, 1998 This paper presents observations with intermediate spectral and spatial resolution along the major and minor axes of the starburst galaxy NGC 253. The spectral ranges analyzed are in the region of the stellar MgIb (5175 A), the near IR CaII triplet (8550 A) absorption features, and the region of the Halpha emission line.

Addressing Systematics in the Traceback Age of the β Pictoris Moving Group
The Astrophysical Journal, 2023 We characterize the impact of several sources of systematic errors on the computation of the traceback age of the β Pictoris moving group ( β PMG). We find that uncorrected gravitational redshift and convective blueshift bias absolute radial velocity ...
