Taking advantage of the Gaia DR1, we combined TGAS parallaxes with theTycho-2 and APASS photometry to calculate the star formation history (SFH) ofthe solar neighbourhood within 250 pc using the colour-magnitude diagramfitting technique. Our dynamically-evolved SFH is in excellent agreement withthat calculated from the Hipparcos catalogue within 80 pc of the Sun, showingan enhanced star formation rate (SFR) in the past ~4 Gyr. We then correct theSFR for the disc thickening with age to obtain a SFR that is representative ofthe whole solar cylinder, and show that even with an extreme correction ourresults are not consistent with an exponentially decreasing SFR as found byrecent studies. Finally, we discuss how this technique can be applied out to ~5kpc thanks to the next Gaia data releases, which will allow us to quantify theSFH of the thin disc, thick disc and halo in situ.
