My CV in pdf format (in Spanish) can be found here. A short version in English is here. 

Several of my works, particularly those related to the influence of solar activity on terrestrial climate, had strong repercussion, not only in the scientific community but also in the mass media and the internet, including my participation in the BBC Documentary Wonders of the Solar System. Several more links can be found here,

This video, and several interviews in television can be found in my YouTube channel.

Research interests and Recent papers

• The HKα Project

 

In 1999 I started a program, the HKα project, to systematically obtain high-resolution spectra of late-type stars, to study in particular chromospheric activity. This is the only ongoing program to systematically study stellar cycles. At present, we have about 5500 spectra of 150 stars, spanning 14 years. If you would like to use this extensive database, please e-mail me.

In this review we present some results of the project, focusing mainly in dM stars.

 

• Optical Robotic Observatory (ORO)

 

We installed four small telescopes in the Argentinian Andes, which are operated remotely. With these telescopes we perform photometric observations of different phenomena, in particular, to study planetary transits. If you would like to collaborate with us, please e-mail me.


• The "Telescopio Horacio Ghielmetti" (THG) is a 16" MEADE RCX 200 telescope, equipped with an Apogee Alta U16 CCD Camera, located at the CASLEO Observatory.
• The "Magnetic Actity and Transiting Exoplanets" (MATE) Telescope is a 16" MEADE LX 200 telescope, equipped with an SBIG Camera, located at the OAFA Observatory.
• We also have two 16" MEADE LX 600 telescopes, equiped with an Apogee and a Moravian cameras, also at the OAFA Observatory.
  
  Both observatories are located in the "El Leoncito" Mountain, at the Argentinian Andes, in the province of San Juan.
