Astrometric follow-up of near-Earth asteroid 2024 YR4 during a Torino scale level 3 alert
Marco Micheli, Maxime Devogèle, Larry Denneau +38
The discovery of 2024 YR4 presented the planetary defense community with the most significant impact threat in almost two decades, reaching level 3 on the Torino scale. The communi…
Star formation in the high-extinction Planck cold clump PGCC G120.69+2.66
Anlaug Amanda Djupvik, João L. Yun, Fernando Comerón
We investigate the star formation occurring in the Planck Galactic cold clump PGCC 120.69+2.66. Near-infrared JHKs images and K-band spectroscopy obtained with NOTCam at the Nordic…
A radical transition in the post-main-sequence system U Equulei
Tomek Kaminski, Mirek R. Schmidt, Anlaug Amanda Djupvik +6
U Equ is an unusual maser-hosting IR source discovered in the 1990s. It was tentatively classified as a post-AGB star with a unique optical spectrum displaying rare emission and ab…
Spectral Type and Geometric Albedo of (98943) 2001 CC21, the Hayabusa2# Mission Target
Jooyeon Geem, Masateru Ishiguro, Mikael Granvik +18
We conducted optical polarimetry and near-infrared spectroscopy of JAXA's Hayabusa2# mission target, (98943) 2001 CC21, in early 2023. Our new observations indicated that this aste…
(3200) Phaethon Polarimetry in the Negative Branch: New Evidence for the Anhydrous Nature of the DESTINY+ Target Asteroid
Jooyeon Geem, Masateru Ishiguro, Jun Takahashi +23
We report on the first polarimetric study of (3200) Phaethon, the target of JAXA's DESTINY mission, in the negative branch to ensure its anhydrous nature and to derive an accur…
Discovery of a pulse-phase-transient cyclotron line in the X-ray pulsar Swift J1808.4-1754 and identification of an optical companion
Alexander Salganik, Sergey S. Tsygankov, Alexander A. Lutovinov +3
In this work, the temporal and spectral properties of the poorly studied X-ray pulsar Swift J1808.41754 were investigated in the 0.8-79 keV energy range based on the data from t…
