How Hot are Hot Stars?: New Temperatures for mid-O types from FUSE data
We analysed high resolution spectra of Galactic O-type stars from the far-UV to the optical. We combined spectra from the Far Ultraviolet Spectroscopic Explorer...
How Important is Rotational Fission in the Trans-Neptunian Region?
We introduce the idea that rotational fission is a possible mechanism in the formation of systems of large TNOs: binary systems, complex systems (Haumea), and...
How Normal Disk Galaxies Ionize their Surroundings
We examine using numerical examples and conservative assumptions, the consequences of the fractal structure of the interstellar medium in a disk galaxy in...
How Planetary Nebulae Shells Interact with their Local Environement
Planetary Nebula (PN) shells and AGB circumstellar envelopes evolve under a wide range of external conditions, from the high ISM densities found in the Galactic...
We present here the outline of the process that any potential GTC observer will need to follow in order to perform their observations. Depending on which of the...
