Vision-Based CNN Prediction of Sunspot Numbers from SDO/HMI Images
Fabian C. Quintero-Pareja, Diederik A. Montano-Burbano, Santiago Quintero-Pareja +1
Sunspot numbers provide the longest continuous record of solar activity and remain a key index for heliophysical research and space-weather applications. Standard sunspot determina…
Complex spectral variability and hints of a luminous companion in the Be star + black hole binary candidate ALS 8814
Kareem El-Badry, Matthias Fabry, Hugues Sana +2
The emission-line binary ALS 8814 was recently proposed as a Be star + black hole (BH) binary based on large-amplitude radial velocity (RV) variations of a Be star and non-detectio…
ASASSN-24fw: An 8-month long, 4.1 mag, optically achromatic and polarized dimming event
R. Forés-Toribio, B. JoHantgen, C. S. Kochanek +20
We discuss ASASSN-24fw, a 13th-magnitude star that optically faded by mag starting in September 2024 after over a decade of quiescence in ASAS-SN. The dimmimg…
Detailed Microwave Continuum Spectra from Bright Protoplanetary Disks in Taurus
Caleb Painter, Sean M. Andrews, Claire J. Chandler +9
We present new observations that densely sample the microwave (4-360 GHz) continuum spectra from eight young systems in the Taurus region. Multi-component, empirical model prescrip…
Symbiotic star candidates in Gaia Data Release 3
Samantha E. Ball, Benjamin C. Bromley, Scott J. Kenyon
Symbiotic stars, binary pairs with a cool giant fueling accretion onto a hot compact companion, offer unique insights to our understanding of stellar evolution. Yet, only a few hun…
Which is the most eccentric binary known? Insights from the 2023/4 pericenter passages of Zeta Boötis and Eta Ophiuchi
Idel Waisberg, Ygal Klein, Boaz Katz
There is a clear dearth of very eccentric binaries among those for which individual eccentricities can be measured. In this paper we report on observations of the two nearby, brigh…
