A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1

Prevalencia de lesiones musculoesqueléticas en jugadores de tenis de mesa
No full textRevista Ciencias Biomédicas Vol.5, Núm. 1 (2014) Pag. 48 - 54Introducción: el tenis de mesa es un deporte complejo, donde son importantes la velocidad, los reflejos, la decisión instantánea, el manejo de los efectos y la técnica. Participan activamente durante la práctica del deporte, la muñeca, el codo, el hombro, la rotación del tronco y el desplazamiento de los miembros inferiores en constante flexión de rodillas. Objetivo: estimar la prevalencia de lesiones en deportistas que practican el tenis de mesa. Metodología: estudio cuantitativo, descriptivo, transversal realizado a deportistas activos y pertenecientes a Clubes afiliados a la Liga de Tenis de Mesa del Departamento de Antioquia, Colombia, con más de un año de dedicación a dicho deporte, mayores de diez años, sin que paralelamente realizaran otros deportes competitivos o tuviesen lesiones producto de deportes o accidentes. Todos participaron de forma voluntaria y no se consideraron deportistas recreativos. La presencia de lesión fue explorada por pregunta realizada dentro de un formulario. No se realizó valoración clínica ni se utilizó método de diagnóstico. No se intentó precisar el tipo de lesión.
Resultados: las regiones anatómicas más afectadas fueron: hombro (28%), rodilla (26%) y región lumbosacra (10%). Las regiones anatómicas donde se informaron lesiones coinciden con lo ampliamente señalado, pero las prevalencias y el orden de frecuencia de lesiones fueron diferentes. Ninguno de los deportistas participantes manifestó traumatismo de globo ocular. Conclusiones: en jugadores de tenis de mesa se encontró que en orden descendente las regiones anatómicas más afectadas fueron: hombro, rodilla y región lumbar
Discovery of an optical counterpart to the hyperluminous X-ray source in ESO 243-49
No full textThe existence of black holes of masses similar to 10(2)-10(5)M(circle dot) has important implications for the formation and evolution of star clusters and supermassive black holes. One of the strongest candidates to date is the hyperluminous X-ray source (HLX1), possibly located in the S0- a galaxy ESO 243-49, but the lack of an identifiable optical counterpart had hampered its interpretation. Using the Magellan telescope, we have discovered an unresolved optical source with R = 23.80 +/- 0.25 mag and V = 24.5 +/- 0.3 mag within HLX1's positional error circle. This implies an average X-ray/optical flux ratio similar to 500. Taking the same distance as ESO 243-49, we obtain an intrinsic brightness M-R = -11.0 +/- 0.3 mag, comparable to that of a massive globular cluster. Alternatively, the optical source is consistent with a main-sequence M star in the Galactic halo (for example an M4.4 star at approximate to 2.5 kpc). We also examined the properties of ESO 243-49 by combining Swift/Ultraviolet/Optical Telescope (UVOT) observations with stellar population modelling. We found that the overall emission is dominated by a similar to 5-Gyr-old stellar population, but the UV emission at approximate to 2000 angstrom is mostly due to ongoing star formation at a rate of similar to 0.03M(circle dot) yr(-1). The UV emission is more intense (at least a 9 sigma enhancement above the mean) north-east of the nucleus, in the same quadrant as HLX1. With the combined optical and X-ray measurements, we put constraints on the nature of HLX1. We rule out a foreground star and a background AGN. Two alternative scenarios are still viable. HLX1 could be an accreting intermediate mass black hole in a star cluster, which may itself be the stripped nucleus of a dwarf galaxy that passed through ESO 243-49, an event which might have caused the current episode of star formation. Or, it could be a neutron star in the Galactic halo, accreting from an M4-M5 donor star
