HARPS3 is being developed as part of the Terra Hunting experiment (a future 10-year radial velocity program to discover Earth-like exoplanets). The instrument design is based on the successful HARPS spectrograph on the 3.6m ESO telescope and HARPS-N on the TNG telescope. The main changes in the design of HARPS3 will be:
- a custom fiber adapter in the Cassegrain spotlight providing a stabilized beam feed and a diameter of 1.4 arcsec in the sky,
- the implementation of a new continuous ow cryostat to keep the CCD temperature very stable,
- detailed characterization of the HARPS3 CCD to map effective pixel positions and thus provide an improved solution of wavelength accuracy,
- an integrated and optimized polarimeter and the instrument integrated in the robotic operation of the telescope.
The robotic operation will optimize our observation program that requires that the target stars be measured on a daily basis.

IAC Participation (Work Packages)
The IAC as a member of the HARPS3 consortium collaborates by adapting the INT Coudé room to house the instrument in conditions of high stability.
For this, it will modernize the supplies available in said room: electricity, data network, lighting, compressed air, glycol water, etc. It will also design and supply a control system and infrastructure for environmental conditions that guarantees high temperature stability.

ARES (High Spectral Resolution) is a coordinated project which attempt to join and consolidate the efforts on instrument developments at high spectral resolution within the IAC. The goal is to launch the scientific programs that the IAC carries out on the search and characterization of exoplanets, in particular Earth-like exoplanets, on the
In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 and 0.45 solar masses. In this context, a team of researchers led by Borja Toledo Padrón, a Severo Ochoa-La Caixa doctoral student at the Instituto de Astrofísica de Canarias (IAC), specializing in the search for planets around this type of stars, has discovered a super-Earth orbiting the star GJ 740, a red dwarf star situated some 36 light yearsAdvertised on
The combination of observations made with the CARMENES spectrograph on the 3.5m telescope at Calar Alto Observatory (Almería), and the HARPS-N spectrograph on the National Galileo Telescope (TNG) at the Roque de los Muchachos Observatory (Garafía, La Palma) has enabled a team from the Instituto de Astrofísica de Canarias (IAC) and from the University of La Laguna (ULL) to reveal new details about this extrasolar planet, which has a surface temperature of around 2000 K.Advertised on
