TL;DR: Observations and physical modelling of a rapidly fading electromagnetic transient in the galaxy NGC 4993, which is spatially coincident with GW170817, indicate that neutron-star mergers produce gravitational waves and radioactively powered kilonovae, and are a nucleosynthetic source of the r-process elements.

TL;DR: In this paper, a photometric and spectroscopic follow-up covering 500 days of the Gaia16aye microlensing event was presented, where the authors employed a full Keplerian binary orbit micro-lensing model combined with the motion of Earth and Gaia around the Sun to reproduce the complex light curve.

TL;DR: In this paper, a photometric and spectroscopic follow-up covering 500 days of the Gaia16aye microlensing event evolution was presented, where the authors employed a full Keplerian binary orbit micro-lensing model combined with the motion of Earth and Gaia around the Sun to reproduce the complex light curve and derived the complete and unique set of orbital parameters of the binary lensing system.

Journal ArticleDOI
Transient behavior of three SU UMa-type dwarf novae; AR Pic, QW Ser and V521 Peg
TL;DR: In this paper , the authors investigated the supercycle lengths of three SU UMa-type dwarf novae: AR Pic, QW Ser and V521 Peg, to determine if they have detectable changes in their supercycles.
