SPHERE dynamical and spectroscopic characterization of HD142527B
R. Claudi, A. -L. Maire, D. Mesa +50
We detect the accreting low-mass companion HD142527B at a separation of 73 mas (11.4 au) from the star. No other companions with mass greater than 10 MJ are visible in the field of…
Spectral and orbital characterisation of the directly imaged giant planet HIP 65426 b
A. C. Cheetham, M. Samland, S. S. Brems +38
HIP 65426 b is a recently discovered exoplanet imaged during the course of the SPHERE-SHINE survey. Here we present new and observations of the planet from the NACO instr…
Evidence for mass accretion driven by spiral shocks onto the white dwarf in SDSS J123813.73-033933.0
A. F. Pala, B. T. Gänsicke, T. R. Marsh +21
We present high-time-resolution photometry and phase-resolved spectroscopy of the short-period () cataclysmic variable SDSS J123813.73-033933.…
The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
Dark energy and Dark matter interaction in light of the second law of thermodynamics
Víctor H. Cárdenas, Daniela Grandón, Samuel Lepe
In the context of thermodynamics we discuss the way inevitable emerge an interaction between dark components, and in this way, provide a mechanism to understand the limits of the L…
Flybys in protoplanetary discs: I. Gas and dust dynamics
Nicolás Cuello, Giovanni Dipierro, Daniel Mentiplay +7
We present 3D smoothed particle hydrodynamics simulations of protoplanetary discs undergoing a flyby by a stellar perturber on a parabolic orbit lying in a plane inclined relative…
