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…
JWST Observations of SN 2023ixf II: The Panchromatic Evolution Between 250 and 720 Days After the Explosion
K. Medler, C. Ashall, P. Hoeflich +60
We present the nebular phase spectroscopic and photometric observations of the nearby hydrogen-rich core-collapse supernova (CC-SN) 2023ixf, obtained through our JWST programs. The…
A Systematic Search for Big Dippers in ASAS-SN
B. JoHantgen, D. M. Rowan, R. Forés-Toribio +6
Dipper stars are extrinsically variable stars with deep dimming events due to extended, often dusty, structures produced by a wide range of mechanisms such as collisions, protoplan…
The Unhurried Universe: A Continued Search for Long Term Variability in ASAS-SN
Sydney Petz, C. S. Kochanek, K. Z. Stanek +4
We search a sample of 5,685,060 isolated sources in the All Sky Automated Survey for SuperNovae (ASAS-SN) with 14.5<g<15 mag for slowly varying sources with brightness changes larg…
ASASSN-13dn: A Luminous and Double-Peaked Type II Supernova
E. Hueichapán, J. L. Prieto, R. Cartier +5
We present observations of ASASSN-13dn, one of the first supernovae discovered by ASAS-SN, and a new member of the rare group of Luminous Type II Supernovae (LSNe II). It was disco…
Citizen ASAS-SN Data Release II: Variable Star Classification Using Citizen Science
O. Kotrach, C. S. Kochanek, C. T. Christy +5
We present the second results from Citizen ASAS-SN, a citizen science project for the All-Sky Automated Survey for Supernovae (ASAS-SN) hosted on the Zooniverse platform. Citizen A…
