FLOR-TORRES, L. M. et al. Connecting the Formation of Stars and Planets. I - Spectroscopic Characterization of Host Stars with TIGRE. Rev. mex. astron. astrofis [online]. 2021, vol.57, n.1, pp.199-216.  Epub 30-Set-2021. ISSN 0185-1101.  https://doi.org/10.22201/ia.01851101p.2021.57.01.15.

In search for a connection between the formation of stars and the formation of planets, a new semi-automatic spectral analysis method using iSpec was developed for the TIGRE telescope installed in Guanajuato, Mexico. TIGRE is a 1.2m robotic telescope, equipped with an Echelle spectrograph (HEROS), with a resolution R ⋍ 20000. iSpec is a synthetic spectral fitting program for stars that allows to determine in an homogeneous way their fundamental parameters: effective temperature, Teff , surface gravity, log g, metallicities, [M=H] and [Fe=H], and rotational velocity, V sin i. In this first article we test our method by analysing the spectra of 46 stars, hosts of exoplanets, obtained with the TIGRE.
