We use these observations to constrain the eccentricity, e, and find that it is consistent with a circular orbit (e < 0.0011).
If confirmed by future observations, this would imply a highly elliptical — or otherwise asymmetric — disk gap with an effective eccentricity of e = ~ 0.3.
In the 1970s and 1980s, some astronomers suggested that observed flare activity or light minima in EV Lac's light curve between flares could have been caused by an eclipsing companion with an orbital period of around 45 years and a high orbital eccentricity (e ~ 0.5)(G. Sh.
Through meticulous observations over the span of 2.5 years, Martinez and collaborators were able to obtain a number of useful measurements for the system, including the pulsar's period (62 ms), the period of the binary (2.62 days), and the system's eccentricity (e = 0.17).
«T» denotes changes in the tilt (or obliquity) of the Earth's axis, «E» denotes changes in the eccentricity of the orbit (due to variations in the minor axis of the ellipse), and «P» denotes precession, that is, changes in the direction of the axis tilt at a given point of the orbit.
«T» denotes changes in the tilt (or obliquity) of the Earth's axis, «E» denotes changes in the eccentricity of the orbit and «P» denotes precession, that is, changes in the direction of the axis tilt at a given point of the orbit.
