Closing the gap to convergence of gravitoturbulence in local simulations
作者：J. Klee , T. F. Illenseer , M. Jung ...
来源：[J].Astronomy & Astrophysics(IF 5.084), 2019, Vol.632EDP Sciences
摘要：Aims. Our goal is to find a converged cooling limit for fragmentation in self-gravitating disks. This is especially interesting for the formation of planets, brown dwarfs, or stars, and the growth of black holes. While investigating the limit, we want to give a clear criteri...

    来源：[J].Astronomy & Astrophysics(IF 5.084), 2019, Vol.632EDP Sciences
    摘要：Context. The radio continuum halos of edge-on spiral galaxies have diverse morphologies, with different magnetic field properties and cosmic ray (CR) transport processes into the halo. Aims. Using the Continuum HAloes in Nearby Galaxies – an EVLA Survey (CHANG-ES) radio cont...

      The water line emission and ortho-to-para ratio in the Orion Bar photon-dominated region
      作者：T. Putaud , X. Michaut , F. Le Petit ...
      来源：[J].Astronomy & Astrophysics(IF 5.084), 2019, Vol.632EDP Sciences
      摘要：Context. The ortho-to-para ratio (OPR) of water in the interstellar medium (ISM) is often assumed to be related to the formation temperature of water molecules, making it a potentially interesting tracer of the thermal history of interstellar gas. Aims. A very low OPR of 0.1...

        Strong lensing models of eight CLASH clusters from extensive spectroscopy: Accurate total mass reconstructions in the cores
        作者：G. B. Caminha , P. Rosati , C. Grillo ...
        来源：[J].Astronomy & Astrophysics(IF 5.084), 2019, Vol.632EDP Sciences
        摘要：We carried out a detailed strong lensing analysis of a sub-sample of eight galaxy clusters of the Cluster Lensing And Supernova survey with Hubble (CLASH) in the redshift range of z cluster = [0.23 − 0.59] using extensive spectroscopic information, primarily from ...

          Carbon depletion observed inside T Tauri inner rims
          作者：M. K. McClure
          来源：[J].Astronomy & Astrophysics(IF 5.084), 2019, Vol.632EDP Sciences
          摘要：Context. The carbon content of protoplanetary disks is an important parameter to characterize planets formed at different disk radii. There is some evidence from far-infrared and submillimeter observations that gas in the outer disk is depleted in carbon, with a correspondin...

            The impact of thermal winds on the outburst lightcurves of black hole X-ray binaries
            作者：Guillaume Dubus , Chris Done , Bailey E. Tetarenko ...
            来源：[J].Astronomy & Astrophysics(IF 5.084), 2019, Vol.632EDP Sciences
            摘要：Context. The observed signatures of winds from X-ray binaries are broadly consistent with thermal winds, which are driven by X-ray irradiation of the outer accretion disc. Thermal winds produce mass outflow rates that can exceed the accretion rate in the disc. Aims. We aim t...

              A radio census of the massive stellar cluster Westerlund 1
              作者：H. Andrews , D. Fenech , R. K. Prinja ...
              来源：[J].Astronomy & Astrophysics(IF 5.084), 2019, Vol.632EDP Sciences
              摘要：Context. Massive stars and their stellar winds are important for a number of feedback processes. The mass lost in the stellar wind can help determine the end-point of the star as a neutron star (NS) or a black hole (BH). However, the impact of mass loss on the post-main sequence ...

                VLT/SPHERE exploration of the young multiplanetary system PDS70

                来源：[J].Astronomy & Astrophysics(IF 5.084), 2019, Vol.632EDP Sciences
                摘要：Context. PDS 70 is a young (5.4 Myr), nearby (~113 pc) star hosting a known transition disk with a large gap. Recent observations with SPHERE and NACO in the near-infrared (NIR) allowed us to detect a planetary mass companion, PDS 70 b, within the disk cavity. Moreover, obse...

                  摘要：Aims. NGC 4631 is an interacting galaxy that exhibits one of the largest, gaseous halos observed among edge-on galaxies. We aim to examine the synchrotron and cosmic-ray propagation properties of its disk and halo emission with new radio continuum data. Methods. Radio contin...

                    Bar pattern speeds in CALIFA galaxies
                    作者：Virginia Cuomo , J. Alfonso Lopez Aguerri , Enrico Maria Corsini ...
                    来源：[J].Astronomy & Astrophysics(IF 5.084), 2019, Vol.632EDP Sciences
                    摘要：Context. About 35% of the nearby disc galaxies host a weak bar for which different formation scenarios, including the weakening of a strong bar and tidal interaction with a companion, have been suggested. Measuring the bar pattern speeds of a sample of weakly barred galaxies is a...
