Asteroids in cometary orbits can be defined as minor planets that do not present cometary activity and has orbits with Tisserand parameter T 3 (typical of...

We are carrying out a study of the physical parameters and excitation of low-ionization structures (LIS) in planetary nebulae (PNe). Since the optical...

Research into the orbital and physical properties near-Earth asteroids (NEAs) is important as these objects can reveal information about the origin and history...

A general overview of the physical properties of the HII regions is presented here, emphasizing the various general models made to explain their structure and...

We use the recent results on solar acoustic modes coming from GOLF and MDI, to demonstrate that we improve the quality of the inversion of the sound speed and...

EST (European Solar Telescope) is a 4-m class solar telescope, which is currently in the conceptual design phase. EST will be located in the Canary Islands and...

I will report on our recent discovery of a wide-spread photometric variability among hot (~20,000 – 30,000 K) extreme horizontal branch (EHB) stars in Galactic...
