Disk Cooling and Wind Lines As Seen In the Spectral Line Evolution of V960 Mon

Adolfo S. Carvalho, Lynne A. Hillenbrand, Jerome Seebeck

We follow up our photometric study of the post-outburst evolution of the FU Ori object V960 Mon with a complementary spectroscopic study at high dispersion that uses time series sp…

The development of HISPEC for Keck and MODHIS for TMT: science cases and predicted sensitivities

Quinn M. Konopacky, Ashley D. Baker, Dimitri Mawet +72

HISPEC is a new, high-resolution near-infrared spectrograph being designed for the W.M. Keck II telescope. By offering single-shot, R=100,000 between 0.98 - 2.5 um, HISPEC will ena…

Transient Corotating Clumps Around Adolescent Low-Mass Stars From Four Years of TESS

Luke G. Bouma, Rahul Jayaraman, Saul Rappaport +5

Complex periodic variables (CPVs) are stars that exhibit highly structured and periodic optical light curves. Previous studies have indicated that these stars are typically disk-fr…

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…

Gaia21bty: An EXor lightcurve exhibiting an FUor spectrum

Michał Siwak, Lynne A. Hillenbrand, Ágnes Kóspál +16

Gaia21bty, a pre-main sequence star that previously had shown aperiodic dips in its light curve, underwent a considerable mag brightening that occurred over a few mo…

Modeling the Multiwavelength Evolution of the V960 Mon System

Adolfo S. Carvalho, Lynne A. Hillenbrand, Franz-Josef Hambsch +7

We study the evolution of the FU Ori object V960 Mon since its outburst, using available multi-wavelength photometric time series over 8 years, complemented by several epochs of mo…
