Occurrence of LINER galaxies within the galaxy group environment
Georgina Coldwell, Luis Pereyra, Sol Alonso +2
We study the properties of a sample of 3967 LINER galaxies selected from SDSS-DR7, respect to their proximity to galaxy groups. The host galaxies of LINER have been analysed and co…
Multi-wavelenth monitoring of the changing-look AGN NGC 2617 during state changes
V. L. Oknyansky, C. M. Gaskell, N. A. Huseynov +18
Optical and near-infrared photometry, optical spectroscopy, and soft X-ray and UV monitoring of the changing-look active galactic nucleus NGC 2617 show that it continues to have th…
MASTER optical detection of the first LIGO/Virgo neutron stars merging GW170817
V. M. Lipunov, E. Gorbovskoy, V. G. Kornilov +30
Following the reported discovery of the gravitational-wave pulse GW170817/ G298048 by three LIGO/Virgo antennae (Abbott et al., 2017a), the MASTER Global Robotic Net telescopes obt…
A gravitational-wave standard siren measurement of the Hubble constant
B. P. Abbott, R. Abbott, T. D. Abbott +1308
The detection of GW170817 in both gravitational waves and electromagnetic waves heralds the age of gravitational-wave multi-messenger astronomy. On 17 August 2017 the Advanced LIGO…
Rayleigh scattering in dense fluid helium
René D. Rohrmann
Iglesias et al. (2002) showed that the Rayleigh scattering from helium atoms decreases by collective effects in the atmospheres of cool white dwarf stars. Their study is here exten…
Signatures of rocky planet engulfment in HAT-P-4. Implications for chemical tagging studies
C. Saffe, E. Jofré, E. Martioli +3
Aims. To explore the possible chemical signature of planet formation in the binary system HAT-P-4, by studying abundance vs condensation temperature Tc trends. The star HAT-P-4 hos…
Evolutionary sequences for hydrogen-deficient white dwarfs
María E. Camisassa, Leandro G. Althaus, René D. Rohrmann +4
We present a set of full evolutionary sequences for white dwarfs with hydrogen-deficient atmospheres. We take into account the evolutionary history of the progenitor stars, all the…
Moreton and EUV Waves Associated with an X1.0 Flare and CME Ejection
Carlos Francile, Fernando M. López, Hebe Cremades +3
A Moreton wave was detected in active region (AR) 12017 on 29 March 2014 with very high cadence with the Halpha Solar Telescope for Argentina (HASTA) in association with an X1.0 fl…
B fields in OB stars (BOB): The magnetic triple stellar system HD 164492C in the Trifid nebula
J. F. Gonzalez, S. Hubrig, N. Przybilla +15
HD 164492C is a spectroscopic triple stellar system that has been recently detected to possess a strong magnetic field. We have obtained high-resolution spectroscopic and spectropo…
