The proper motion measurements for 143 previously known L and T dwarfs are presented. From this sample we identify and discuss eight high-velocity L dwarfs. We...
Proper Motions of Local Group Dwarf Spheroidal Galaxies I: First Ground-Based Results for Fornax
In this article we present in detail the methodology and the first results of a ground-based program to determine the absolute proper motion of the Fornax dwarf...
We present new z- and H-band photometry and proper motion measurements for the five candidate very-low-mass T-type objects we recently proposed to be members of...
Properties of a New Group of Cosmic Nuclei: Results from the Alpha Magnetic Spectrometer on Sodium, Aluminum, and Nitrogen
We report the properties of sodium (Na) and aluminum (Al) cosmic rays in the rigidity range 2.15 GV to 3.0 TV based on 0.46 million sodium and 0.51 million...
We analyze the properties of a sample of galaxies identified in a 21cm, H I-line survey of selected areas in the Perseus-Pisces supercluster and its foreground...
Properties of barred galaxies with the environment. I. The case of the Virgo cluster
Context. Barred structures are widespread in a considerable fraction of galactic disks, spanning diverse environments and galaxy luminosities. The environment...
Properties of bars and bulges in the Hubble sequence
Properties of bars and bulges in the Hubble sequence are discussed, based on an analysis of 216 disc galaxies of S0-Sm types (S0s from the Near-Infrared S0...
Properties of central stars of planetary nebulae with distances in Gaia DR2
Context. We have compiled a catalogue of central stars of planetary nebulae (CSPN) with reliable distances and positions obtained from Gaia Data Release 2 (DR2)...
Properties of convective motions in facular regions
Aims: We study the properties of solar granulation in a facular region from the photosphere up to the lower chromosphere. Our aim is to investigate the...
