Context. The kinematics of planetary nebulae in external galaxies and in our own is a clue for understanding the behavior of the low- and intermediate-mass...
Kinematical analysis of the ionized gas in the nuclear region of NGC 4214
We present in this paper a detailed study of the kinematical properties of the ionized gas around the young massive star clusters in the nucleus of NGC 4214...
Kinematical study of ring nebulae around galactic Wolf-Rayet stars.
High resolution spectroscopic observations have been obtained for the ring nebulae around the galactic Wolf-Rayet stars WR 113 (CV Ser), WR 116, WR 128 (MR 95)...
Kinematics and chemical properties of the Galactic stellar populations. The HARPS FGK dwarfs sample
Aims: We analyzed chemical and kinematical properties of about 850 FGK solar neighborhood long-lived dwarfs observed with the HARPS high-resolution spectrograph...
Context. 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...
Kinematics of planet-host stars and their relation to dynamical streams in the solar neighbourhood
We present a detailed study on the kinematics of metal-rich stars with and without planets, and their relation to the Hyades, Sirius and Hercules dynamical...
Kinetic power of quasars and statistical excess of MOJAVE superluminal motions
Aims: The MOJAVE (MOnitoring of Jets in AGN with VLBA Experiments) survey contains 101 quasars with a total of 354 observed radio components that are different...
KMT-2021-BLG-0322: Severe degeneracy between triple-lens and higher-order binary-lens interpretations
Aims: We investigate the microlensing event KMT-2021-BLG-0322, for which the light curve exhibits three distinctive sets of caustic-crossing features. It is...
KMT-2021-BLG-1077L: The fifth confirmed multiplanetary system detected by microlensing
Aims: The high-magnification microlensing event KMT-2021-BLG-1077 exhibits a subtle and complex anomaly pattern in the region around the peak. We analyze the...
