First Detection of HC5N in a Class II Disk around TW Hya

Steven C. Wampler, Ryan A. Loomis, Amina Diop +9

Over the last decade of ALMA's operation the molecular inventory of protoplanetary disks has expanded rapidly, revealing a diverse set of nitrogen-bearing organics and carbon-chain…

Spatial and spectral constraints on resolved mass-loss of the massive Post-RSG star IRAS 17163-3907 and its Fried Egg Nebula

E. Koumpia, A. Cikota, W. -J. de Wit +12

The fate of massive stars during the latest stages of their evolution is highly dependent on their mass-loss rate and geometry. These processes have a significant influence on star…

Magnetohydrodynamic instabilities in stellar radiative regions. I. Linear study of shear-driven instabilities

V. Durepaire, L. Petitdemange, K. Belkacem +4

This paper is the first in a series investigating magnetohydrodynamic instabilities that may contribute to angular-momentum transport and magnetic-field evolution in stellar radiat…

Evolution of the Accretion Rate of Young Intermediate Mass Stars: Implications for Disk Evolution and Planet Formation

Sean D. Brittain, Joshua W. Kern, Gwendolyn Meeus +1

This work presents a study of the evolution of the stellar accretion rates of pre-main-sequence intermediate-mass stars. We compare the accretion rate of the younger intermediate-m…

Asteroseismic Imprints of Mass Transfer in Binary Stars: Probing the Interiors of Donors and Accretors with Gravity and Acoustic Modes

Tao Wu, Zhao Guo, Yan Li

Context. The synergy between close binary stars and asteroseismology enables constraints on mass-transfer episodes and their consequences for internal structure, rotation profiles,…
