Optical and Radio Observations of the T Tauri Binary KH 15D (V582 Mon): Stellar Properties, Disk Mass Limit and Discovery of a CO Outflow
Rachel A. Aronow, William Herbst, A. Meredith Hughes +2
We present VRIJHK photometry of the KH 15D T Tauri binary system for the 2015/16 and 2016/17 observing seasons. For the first time in the modern (CCD) era we are seeing Star B full…
Spitzer Observations of Long Term Infrared Variability Among Young Stellar Objects in Chamaeleon I
Kevin M. Flaherty, Lindsay DeMarchi, James Muzerolle +5
Infrared variability is common among young stellar objects, with surveys finding daily to weekly fluctuations of a few tenths of a magnitude. Space-based observations can produce h…
Seeing Through the Ring: Near-Infrared Photometry of V582 Mon (KH 15D)
Nicole A. Arulanantham, William Herbst, Ann Marie Cody +10
We examine the light and color evolution of the T Tauri binary KH 15D through photometry obtained at wavelengths between 0.55 and 8.0 m. The data were collected with ANDICAM on…
CSI 2264: Characterizing Young Stars in NGC 2264 with Stochastically Varying Light Curves
John Stauffer, Ann Marie Cody, Luisa Rebull +25
We provide CoRoT and Spitzer light curves, as well as broad-band multi-wavelength photometry and high resolution, multi- and single-epoch spectroscopy for 17 classical T Tauris in…
Physical parameters and long-term photometric variability of V1481 Ori, a SB2 member of Orion Nebula Cluster with an accreting component
Sergio Messina, Padmakar Parihar, Katia Biazzo +5
We present the results of our analysis on V1481 Ori (JW 239), a young SB2 in the Orion Nebula Cluster with a circumbinary disc accreting on the lower-mass component. The analysis i…
CSI 2264: Probing the inner disks of AA Tau-like systems in NGC 2264
Pauline T. McGinnis, Silvia H. P. Alencar, Marcelo M. Guimaraes +20
The classical T Tauri star AA Tau presented photometric variability attributed to an inner disk warp, caused by the interaction between the inner disk and an inclined magnetosphere…
