Dynamical Analysis of the HD 169142 Planet-forming Disk: Twelve Years of High-contrast Polarimetry

The Astronomical Journal
We present a dynamical analysis of the HD 169142 planet-forming disk based on high-contrast polarimetric imaging over a twelve-year observational period, offering insights into its disk evolution and planet–disk interactions.

exoALMA. III. Line-intensity Modeling and System Property Extraction from Protoplanetary Disks

The Astrophysical Journal Letters
The ALMA large program exoALMA offers a unique window into the three-dimensional physical and dynamical properties of 15 circumstellar disks where planets may be actively forming. Here, we present an analysis methodology to map the gas disk structure and

An Equipotential Disk Model with Irradiation for Nova-like Variables

The Astrophysical Journal
The reflection effect is here incorporated within an earlier analytic binary system light- and velocity-curve model that includes a circumstellar equipotential disk.

Doppler Tomography of the Circumstellar Disk of the Be Star κ Draconis

Galaxies
κ Draconis is a binary system with a classical Be star as the primary component. Its emission-line spectrum consists of hydrogen lines, notably the Hα line with peak intensity ratio (V/R) variations phase-locked with the orbital period P = 61.55 days ...
