Twenty-Five Years of Accretion onto the Classical T Tauri Star TW Hya
Gregory J. Herczeg, Yuguang Chen, Jean-Francois Donati +39
Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time…
The Accretion History of EX Lup: A Century of Bursts, Outbursts, and Quiescence
Mu-Tian Wang, Gregory J. Herczeg, Hui-Gen Liu +11
EX Lup is the archetype for the class of young stars that undergoes repeated accretion outbursts of mag at optical wavelengths and that last for months. Despite extensive…
Introducing the Condor Array Telescope. 1. Motivation, Configuration, and Performance
Kenneth M. Lanzetta, Stefan Gromoll, Michael M. Shara +4
The "Condor Array Telescope" or "Condor" is a high-performance "array telescope" comprised of six apochromatic refracting telescopes of objective diameter 180 mm, each equipped wit…
V5856 Sagittarii/2016: Broad Multi-Epoch Spectral Coverage of a Sustained High Luminosity Nova
Robert Williams, Frederick M. Walter, Richard J. Rudy +4
Nova V5856 Sagittarii is unique for having remained more than nine magnitudes above its pre-outburst brightness for more than six years. Extensive visible and IR spectra from the t…
The Nova KT Eri Is a Recurrent Nova With a Recurrence Time-Scale of 40-50 Years
Bradley E. Schaefer, Frederick M. Walter, Rebekah Hounsell +1
KT Eridani was a very fast nova in 2009 peaking at V=5.42 mag. We marshal large data sets of photometry to finally work out the nature of KT Eri. From the TESS light curve, as conf…
Revealing Ionization Conditions of Sz 102 with Spatially Resolved [Ne III] Microjets
Chun-Fan Liu, Hsien Shang, Gregory J. Herczeg +1
Forbidden neon emission lines from small-scale microjets can probe high-energy processes in low-mass young stellar systems. We obtained spatially resolved [Ne III] spectra of the m…
