In order to develop a reliable method of distance determination of W UMa-type stars, a catalogue of light curve solutions of 159 systems has been compiled. The...
Distances to globular cluster-rich UDGs: The case of NGC1052-DF2
Some ultra-diffuse galaxies (UDGs) are known to host very large globular cluster (GC) systems, clearly exceeding the expectations for galaxies with such low...
Distances to Planetary Nebulae: A Key to Galactic Structure and Evolution
The knowledge of accurate distances to Planetary Nebulae (PNe) is necesary in order to improve the determination of some physical quantities such as the nebular...
This paper presents the IAC (Instituto de Astrofisica de Canaries, Spain) proposal of a distributed control system intended for the active support of a 8 m...
Distributed object-oriented telescope control system for the GTC
The Gran Telescopio Canarias (GTC) project office is in charge of the construction of an optical/IR 10-meter class telescope at the Observatorio del Roque de...
Distributed X-Ray Data and Distributed Analysis Tools
X-ray data and analysis packages can now be distributed directly to the desks of the user community using CDROMs and portable, familiar analysis packages (like...
Mg II emissions in the IUE spectra of 91 cool stars are analyzed in a systematic search for interstellar components. About 60 percent of the stars show evidence...
