Distance distribution of KYSO sources (blue bars) and of sources classified as Gaia DR3 YSOs (red bars). The values show strong similarities, except that there are more KYSOs within 100 pc of the Sun. These nearby KYSO sources (87 have distances of smaller than 100 pc) are mostly members of the TW Hydrae association. There are also three strong peaks in the distance distribution. The first one, between ∼125 and ∼175 pc, corresponds to the Ophiuchus, Sco OB2 association, and Taurus regions. The second strong peak is seen at distances of between ∼300 and ∼500 pc. The vast majority of these sources are located in Orion. The third peak is between ∼300 and ∼1000 pc. These sources are also seen towards Orion and towards the Galactic midplane as well.
