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...
Properties of Cosmic Helium Isotopes Measured by the Alpha Magnetic Spectrometer
Precision measurements by the Alpha Magnetic Spectrometer (AMS) on the International Space Station of He 3 and He 4 fluxes are presented. The measurements are...
Properties of Cosmic-Ray Sulfur and Determination of the Composition of Primary Cosmic-Ray Carbon, Neon, Magnesium, and Sulfur: Ten-Year Results from the Alpha Magnetic Spectrometer
We report the properties of primary cosmic-ray sulfur (S) in the rigidity range 2.15 GV to 3.0 TV based on 0.38 ×10 6 sulfur nuclei collected by the Alpha...
We present the precision measurement of 2824 daily helium fluxes in cosmic rays from May 20, 2011 to October 29, 2019 in the rigidity interval from 1.71 to 100...
Properties of dusty tori in active galactic nuclei - I. The case of SWIRE/SDSS quasars
We derive the properties of dusty tori in active galactic nuclei from the comparison of observed spectral energy distributions (SEDs) of SDSS quasars and a...
Properties of extragalactic thick discs recovered from ultra-deep Stripe82 imaging
Context. Thick discs can give invaluable information on the formation and evolution history of galaxies as most, if not all, disc galaxies have a thin...
Properties of FIRBACK-ELAIS 175-μm sources in the ELAIS N2 region
We report on a search for the optical counterparts of 175-μm selected sources from the Far-Infrared Background (FIRBACK) survey in the European Large Area ISO...
