Ultracool Dwarfs in deep extragalactic surveys using the Virtual Observatory: ALHAMBRA and COSMOS

E. Solano, M. C. Gálvez-Ortiz, E. L. Martín +8

Ultracool dwarfs encompass a wide variety of compact stellar-like objects with spectra classified as late-M, L, T and Y. Most of them have been discovered using wide-field imaging…

Advances in Understanding High-Mass X-ray Binaries with INTEGRAL and Future Directions

Peter Kretschmar, Felix Fürst, Lara Sidoli +48

High mass X-ray binaries are among the brightest X-ray sources in the Milky Way, as well as in nearby Galaxies. Thanks to their highly variable emissions and complex phenomenology,…

The decline of astronomical research in Venezuela

Nestor Sanchez

During the last 15 years the number of astronomy-related papers published by scientists in Venezuela has been continuously decreasing, mainly due to emigration. If rapid corrective…

K2-280b -- a low density warm sub-Saturn around a mildly evolved star

Grzegorz Nowak, Enric Palle, Davide Gandolfi +57

We present an independent discovery and detailed characterisation of K2-280b, a transiting low density warm sub-Saturn in a 19.9-day moderately eccentric orbit (e = 0.35_{-0.04}^{+…

An order-adaptive compact approximation Taylor method for systems of conservation laws

H. Carrillo, E. Macca, G. Russo +2

We present a new family of high-order shock-capturing finite difference numerical methods for systems of conservation laws. These methods, called Adaptive Compact Approximation Tay…

A catalogue of open cluster radii determined from Gaia proper motions

Nestor Sanchez, Emilio Alfaro, Fatima Lopez-Martinez

In this work we improve a previously published method to calculate in a reliable way the radius of an open cluster. The method is based on the behaviour of stars in the proper moti…

Multi-wavelength observations of PSRJ 2032+4127 during the 2017 periastron passage

Maria Chernyakova, Denys Malyshev, Pere Blay +2

PSRJ 2032+4127 is only the second known gamma-ray binary where it is confirmed that a young radio pulsar is in orbit around a Be-star. The interaction of the pulsar wind with the m…
