LOS ESPECTROGRAFOS DE ALTA RESOLUCION Y GRAN ESTABILIDAD INSTALADOS EN TELESCOPIOS DE GRAN DIAMETRO, COMO EL VLT Y EL GTC, NOS PERMITIRAN EXTRAER CON DETALLE INFORMACION DINAMICA Y QUIMICA DE ESTRELLAS EN DISTINTOS LUGARES DE LA VIA LACTEA. EL ESPECTROGRAFO ESPRESSO, DE CUYO EQUIPO CIENTIFICO FORMAN PARTE LOS IPS, Y QUE SE INSTALARA EN LOS TELESCOPIOS VLT DURANTE EL INVIERNO DE 2017, NOS PERMITIRA DESCUBRIR Y CARACTERIZAR PLANETAS SIMILARES A LA TIERRA EN SUS ZONAS DE HABITABILIDAD, EN PARTICULAR EN TORNO A ESTRELLAS BRILLANTES Y CERCANAS DE TIPO SOLAR, Y POR TANTO CON POSIBILIDADES DE ALBERGAR VIDA. ESTAS EXOTIERRAS SERAN CANDIDATAS PARA EL ESTUDIO DE SUS ATMOSFERAS CON LA SIGUIENTE GENERACION DE INSTRUMENTS, COMO HIRES EN EL ELT, EN EL CUAL ESTAMOS INVOLUCRADOS._x000D_ _x000D_ EL ESPECTROGRAFO HORS, QUE SE IINSTALARA EN EL GTC DURANTE EL INVIERNO DE 2017, NOS PERMITIRA INVESTIGAR LA QUIMICA DE LAS ESTRELLAS MAS POBRES EN METALES DEL HALO DE LA VIA LACTEA, IDENTIFICADAS A PARTIR DE ESPECTROS EN GRANDES BASES DE DATOS COMO SDSS, O LAMOST. LA COMPOSICION DE LAS ATMOSFERAS DE ESTAS ESTRELLAS PROPORCIONA INFORMACION DE PRIMERA MANO SOBRE LAS PRIMERAS ESTRELLAS, AQUELLAS QUE SE FORMARON POCO DESPUES LA GRAN EXPLOSION CON METALICIDAD CERO, Y LA NUCLEOSINTESIS EN LAS SUPERNOVAS QUE EXPLOTARON AL FINAL DE SUS VIDAS._x000D_ LOS OBJETIVOS ESPECIFICOS DE ESTE PROYECTO SON:_x000D_ _x000D_ 1) LLEVAR A CABO LA EXPLOTACION CIENTIFICA DEL ESPECTROGRAFO ULTRA-ESTABLE DE MUY ALTA RESOLUCION ESPRESSO, EJECUTANDO LAS NOCHES DE TIEMPO GARANTIZADO (GTO), EN PARTICULAR, DESCUBRIR PLANETAS DE TIPO ROCOSO EN LA ZONA DE HABITABILIDAD,_x000D_ 2) LLEVAR A CABO LA EXPLOTACION CIENTIFICA DE HARPS EQUIPADO CON EL LASER COMB (LFC), Y HARPS-N CON PROGRAMAS DE OBSERVACION INTENSIVOS, INCLUIDOS LOS PROGRAMAS GARANTIZADOS (GTO) CONCEDIDOS PARA HARPS-LFC CON EL OBJETIVO DE DETECTAR SUPER-TIERRAS Y TIERRAS ORBITANDO ESTRELLAS DE TIPO G, K Y M,_x000D_ 3) OBTENER ESPECTROSCOPIA DE ALTA RESOLUCION CON EL ESPECTROGRAFO HORS, Y OTROS ESPECTROGRAFOS DE ALTA RESOLUCION EN LOS TELESCOPIOS VLT, KECK, Y SUBARU, DE LAS ESTRELLAS MAS PRIMITIVAS DEL HALO DE LA VIA LACTEA DESCUBIERTAS POR NUESTRO EQUIPO DE INVESTIGACION,_x000D_ 4) FINALIZAR EL DESARROLLO DEL HAZ DE FIBRAS DEL INSTRUMENTO NIRPS PARA EL TELESCOPIO 3.6M DE LA ESO, CUYA INSTALACION ESTA PREVISTA PARA 2019, E INICIAR SU EXPLOTACION CIENTIFICA HACIENDO USO DEL TIEMPO GARANTIZADO,_x000D_ 5) LIDERAR EL DESARROLLO DEL HAZ DE FIBRAS PARA EL ESPECTROGRAFO DE ALTA RESOLUCION Y ESTABILIDAD HIRES PARA EL FUTURO TELESCOPIO EUROPEO DE 39-M ELT DE LA ESO, Y PARTICIPAR EN EL DESARROLLO DEL BRAZO VISIBLE DEL ESPECTROGRAFO.

HIGH RESOLUTION STABLE SPECTROGRAPHS, COUPLED TO LARGE-SIZE TELESCOPES SUCH AS VLT OR GTC, WILL ALLOW US TO EXTRACT IN DETAIL THE DYNAMICAL AND CHEMICAL INFORMATION OF STARS ACROSS THE MILKY WAY. THE ESPRESSO SPECTROGRAPH, IN WHOSE SCIENCE TEAM THE PIS ARE INVOLVED, AND WHICH WILL BE INSTALLED AT THE VLT IN WINTER 2017, WILL ALLOWS US TO DISCOVER AND CHARACTERIZE PLANETS SIMILAR TO EARTH IN THE HABITABILITY ZONE, IN PARTICULAR AROUND BRIGHT AND NEARBY SOLAR-LIKE STARS, AND THEREFORE WITH POSSIBILITIES OF HOSTING LIFE. THESE EXO-EARTHS ARE CANDIDATES FOR THE STUDY OF THEIR ATMOSPHERES WITH THE NEXT GENERATION OF INSTRUMNETS, SUCH AS HIRES ON THE ELT, ON WHICH WE ARE INVOLVED._x000D_ _x000D_ THE HORS SPECTROGRAPH, TO BE INSTALLED IN GTC IN WINTER 2017, WILL ALLOW US TO STUDY THE CHEMISTRY OF THE MOST METAL-POOR STARS IN THE HALO OF THE MILKY WAY, WHICH HAVE BEEN IDENTIFIED FROM SPECTRA IN LARGE DATA BASES SUCH AS SDSS OR LAMOST. THE CHEMICAL COMPOSITION OF THE ATMOSPHERES OF THESE STARS PROVIDES FIRST-HAND INFORMATION ABOUT THE FIRST STARS, THOSE THAT FORMED SHORTLY AFTER THE BIG BANG WITH ZERO METALLICITY, AND THE NUCLEOSYNTHESIS IN THE SUPERNOVAE THAT WENT OFF AT THE END OF THEIR LIVES._x000D_ _x000D_ THE MAIN GOALS OF THIS PROJECT ARE:_x000D_ _x000D_ 1) TO CARRY OUT THE SCIENTIFIC EXPLOITATION OF THE ULTRA-STABLE HIGH-RESOLUTION SPECTROGRAPH ESPRESSO, USING THE GUARANTEED TIME, AND IN PARTICULAR TO DISCOVER ROCKY PLANETS IN THE HABITABLE ZONE._x000D_ 2) TO CARRY OUT THE SCIENTIFIC EXPLOITATION OF HARPS EQUIPPED WITH THE LASER COMB (LFC) AND HARPS-N THROUGH INTENSIVE OBSERVING PROGRAMS, INCLUDING THE GUARANTEED TIME FOR HARPS-LFC, AIMED TO DETECT SUPER-EARTH AND EARTH-LIKE PLANETS AROUND GKM-TYPE STARS._x000D_ 3) TO PERFORM HIGH-RESOLUTION SPECTROSCOPY WITH HORS, AND OTHER HIGH-RESOLUTION SPECTROGRAPHS AVAILABLE ON THE VLT, KECK AND SUBARU, OF THE MOST PROMITIVE STARS IN THE HALO OF THE MILKY WAY DISCOVERED BY OUR RESEARCH TEAM._x000D_ 4) TO FINISH THE DEVELOPMENT OF THE FIBER LINK FOR THE NIRPS INSTRUMENT FOR THE ESO 3.6M TELESCOPE, WHOSE INSTALLATION IS PLANNED FOR 2019, AND START ITS SCIENTIFIC EXPLOITATION TAKING ADVANTAGE OF THE GUARANTEED TIME._x000D_ 5) TO LEAD THE DEVELOPMENT OF THE FIBER LINK FOR HIRES, THE HIGH-RESOLUTION ULTRA-STABLE SPECTROGRAPH FOR THE FUTURE 39-M ESO ELT, AND TO PARTICIPATE IN THE DEVELOPMENT OF THE OPTICAL ARM OF THE SPECTROGRAPH.
