Probing Accretion and Outflow in V1180 Cas through High-Resolution Optical Spectroscopy
Tarak Chand, Saurabh Sharma, Koshvendra Singh +9
We present an analysis of a high-resolution optical spectrum of V1180 Cas obtained with HIRES at the W. M. Keck Observatory during a bright photometric state of the source. The spe…
Hot water emission during an outburst in a classical T Tauri star
Zhen Guo, Javier Osses, Vitor Fermiano +34
In this paper, we present observations of an eruptive young star in the Rosette Nebula, identified by the Gaia Science Alerts system using Gaia time series data. We aim to investig…
Searching for GEMS: Discovery of the Nearby Post-Common-Envelope Binary System TIC-460388167
Alexandra Boone, Henry A. Kobulnicky, Caleb I. Cañas +11
Short-period white dwarf+main-sequence binaries are Post-Common-Envelope Binaries (PCEB) that have survived a common envelope phase. Such systems, if detached and eclipsing, enable…
Gaia24ccy: An outburst followed the footsteps of its predecessor
Koshvendra Singh, Joe P. Ninan, Zhen Guo +25
Accretion-driven outbursts in young stellar objects remain poorly understood, largely limited by a statistically small sample of closely followed-up events. This underscores the im…
Stellar and orbital characterization of three low mass M dwarf binary stars with dynamical spectroscopy from the Habitable Zone Planet Finder
Suhani Surana, Chad F. Bender, Caleb I. Cañas +13
Theoretical models of low-mass stars continue to be discrepant with observations when used to examine the mass-radius relationship and other physical parameters of individual stars…
Unveiling the Dual Nature of V1180 Cas: UXor-like Dips and EXor-like Bursts Across a Decade
Tarak Chand, Saurabh Sharma, Koshvendra Singh +15
We present a detailed analysis of the long-term photometric and spectroscopic evolution of V1180 Cas over a decade, aiming to identify the dominant mechanisms behind its variabilit…
