DOI: 10.1051/0004-6361/202038013
Abstract: Multi-epoch observations have revealed the variability of pre-main sequence stars and/or their environment. Moreover, structures in orbital motion around the central star, resulting from planet-disk interaction, are predicted to cause temporal variations in the brightness… read more here.

DOI: 10.1109/lra.2024.3498780
Abstract: The LiDAR-inertial odometry (LIO) and the ultra-wideband (UWB) have been integrated to achieve driftless positioning in global navigation satellite system (GNSS)-denied environments. However, the UWB may be affected by systematic range errors (such as the… read more here.
