PublicaciónA Case against a Significant Detection of Precession in the Galactic Warp
Recent studies of warp kinematics using Gaia DR2 data have produced detections of warp precession for the first time, which greatly exceeds theoretical...

PublicaciónA search for new objects in the transition phase between AGB-stars and planetary nebulae
Preliminary results are presented from a spectroscopy survey of IRAS sources with colors similar to those of planetary nebulae. Two new planetary nebulae, some...
