H-alpha observations of zeta Tauri
E. Pollmann, Th. Rivinius
TL;DR
This paper presents long-term H-alpha observations of zeta Tauri, revealing a 69-day intermediate timescale in V/R variations, contributing to understanding the star's disk dynamics.
Contribution
It provides extended observational data and identifies a specific intermediate timescale in the V/R variations of zeta Tauri's disk.
Findings
Detected a 69-day timescale in V/R variations.
Extended the monitoring period of zeta Tauri's disk.
Observed persistent H-alpha line variations.
Abstract
We report H-alpha observations of zeta Tauri, taken between late 2000 and early 2006. Next to extending existing long-term montioring of the disk state of this star we report an intermediate timescale of about 69 days to be present in the V/R variations of the Halpha line. The observational data will be published together with this manuscript.
