Adaptive optics plans for the Gran Telescopio Canarias
The large telescope planned for the Observatorio del Roque de los Muchachos will include an adaptive optics (AO) facility, designed to provide diffraction...
Addendum: Optical re-brightening of the black hole transient XTE J1752-223
We observed the black hole candidate XTE J1752-223 (ATel #2258) with the William Herschel Telescope (WHT) and the ACAM imager/spectrograph at the Observatorio...
Additively manufactured flexure for astronomy instrumentation
Additive Manufacturing (AM) has several potential advantages for astronomical instrumentation: particularly the ability to create custom parts with optimised...
Addressing the Question Posed by the Of?p Stars: HD191612
There are three known Of?p stars in our galaxy, they are the well known peculiar stars HD108, HD148937 and HD191612. The question mark in their spectral...
Advanced stereoscopic gamma-ray shower analysis with the MAGIC telescopes
The MAGIC experiment was upgraded to a two-telescope system in 2009. Unlike other Imaging Air Cherenkov Telescope arrays, MAGIC has operated for five years...
Advances in solar rotation rate inferences: Unstructured grid inversions and improved rotational splittings
We present a new inversion methodology that adapts the inversion grid in both radius and co-latitude to the data set and solves the inversion problem through an...
Advances in the development of FRIDA's mechanisms control system and house-keeping
FRIDA will be a near infrared imager and integral field spectrograph covering the wavelength range from 0.9 to 2.5 microns. Primary observing modes are: direct...
Advances on the telescope structure conceptual design of the European Solar Telescope
The works described in the current paper correspond to some exploratory advances that were performed by ESTEYCO in close collaboration with IAC on the European...
