GD 358: The Case For Oblique Pulsation And Temperature Change
MetadataShow full item record
We provide multiple lines of evidence that GD 358's convection zone was much thinner in 1996 than in 2006 and we interpret this as a result of a short-lived increase in its surface temperature. In addition, we find strong evidence of oblique pulsation using two sets of evenly split triplets in the 2006 data. This marks the first time that oblique pulsation has been identified in a variable white dwarf star as well as the first time that a temperature change has been observed in a single white dwarf.
