Notes

In SIMBAD (Wenger et al., 2000), it is classified as a YSO based on the work of Megeath et al. (2012). It is included in the list of YSO candidates in Cottle et al. (2018). Object IRAS 05451+0037 to the east of LkHA 316 was analyzed and confirmed as a YSO by Hillenbrand et al. (2012). It is identified as a T Tauri star in Herbig & Bell (1988).
