TU Tau B: The Peculiar 'Eclipse' of a possible proto-Barium Giant
Richard O. Gray, Christopher J. Corbally, Michael M. Briley +26
TU Tau (= HD 38218 = HIP 27135) is a binary system consisting of a C-N carbon star primary and an A-type secondary. We report on new photometry and spectroscopy which tracked the r…
Combined Spectroscopic and Photometric Analysis of Flares in the Dwarf M Star EV Lacertae
David Boyd, Robert Buchheim, Sean Curry +6
We report results of an observing campaign to study the dwarf M flare star EV Lacertae. Between October 2021 and January 2022 we obtained concurrent B band photometry and low resol…
The Rise and Fall of the King: The Correlation between FO Aquarii's Low States and the White Dwarf's Spindown
Colin Littlefield, Peter Garnavich, Mark R. Kennedy +45
The intermediate polar FO Aquarii (FO Aqr) experienced its first-reported low-accretion states in 2016, 2017, and 2018, and using newly available photographic plates, we identify p…
A Tight Connection between Gamma-Ray Outbursts and Parsec-Scale Jet Activity in the Quasar 3C 454.3
Svetlana G. Jorstad, Alan P. Marscher, Paul S. Smith +42
We analyze the multifrequency behavior of the quasar 3C 454.3 during three prominent γ-ray outbursts: 2009 Autumn, 2010 Spring, and 2010 Autumn. The data reveal a repeating pattern…
Modern observations of Hubble's first-discovered Cepheid in M31
M. Templeton, A. Henden, W. Goff +9
We present a modern ephemeris and modern light curve of the first-discovered Cepheid variable in M31, Edwin Hubble's M31-V1. Observers of the American Association of Variable Star…
The brightest gamma-ray flaring blazar in the sky: AGILE and multi-wavelength observations of 3C 454.3 during November 2010
S. Vercellone, E. Striani, V. Vittorini +84
Since 2005, the blazar 3C 454.3 has shown remarkable flaring activity at all frequencies, and during the last four years it has exhibited more than one gamma-ray flare per year, be…
