We present observations taken with the Advanced Stokes Polarimeter (ASP) in active-region plages and study the frequency distribution of the magnetic field...
Active Region Morphologies Selected from Near-side Helioseismic Data
We estimate the morphology of near-side active regions using near-side helioseismology. Active regions from two data sets, Air Force Data Assimilative...
Active star formation regions at the edge of the LMC Bar: NGC 1850 and NGC 1858
We present UBV Johnson CCD photometry of two young clusters of the Large Magellanic Cloud (LMC), namely NGC 1850 and NGC 1858, which are located at the NW part...
Activity at the Deuterium-burning Mass Limit in Orion
We report very intense and variable Hα emission (pseudoequivalent widths of ~180 and 410 Å) of S Ori 55, a probable free-floating, M9-type substellar member of...
Activity from the Be/X-ray binary system V0332+53 during its intermediate-luminosity outburst in 2008
Aims: We present a study of the Be/X-ray binary system V 0332+53 with the main goal of characterizing its behaviour mainly during the intermediate-luminosity X...
Activity of Comet 103P/Hartley 2 at the time of the EPOXI mission fly-by
Comet 103P/Hartley 2 was observed on November 1-6, 2010, coinciding with the fly-by of the space probe EPOXI. The goal was to connect the large scale phenomena...
Activity of the Jupiter co-orbital comet P/2019 LD<SUB>2</SUB> (ATLAS) observed with OSIRIS at the 10.4 m GTC
Context. The existence of comets with heliocentric orbital periods close to that of Jupiter (i.e., co-orbitals) has been known for some time. Comet 295P/LINEAR...

RESUMEN: En este trabajo se examina, desde la perspectiva de la Astronomía Cultural, si las iglesias románicas del Camino de Santiago siguen un patrón de...
Adapting astronomical source detection software to help detect animals in thermal images obtained by unmanned aerial systems
In this paper we describe an unmanned aerial system equipped with a thermal-infrared camera and software pipeline that we have developed to monitor animal...
