plot_superbursts_constraints

macro_lightning.plot.plot_superbursts_constraints(points1: Union[None, Sequence] = None, points2: Union[None, Sequence] = None, label=False)[source]

Plot Constraints from Superbursts in Neutron Stars.

For sufficiently large cross-sections, the linear energy deposition could produce observable signals if a macro were to pass through compact objects such as neutron stars in the form of thermonuclear runaway, leading to a superburst. New constraints are inferred from the low mass X-ray binary 4U 1820-30, in which more than a decade passed between successive superbursts [1].

Parameters
points1ndarray, optional

N x 2 array for a Polygon if None (default) will load from load_superbursts_polygons()

points2ndarray, optional

N x 2 array for a Polygon if None (default) will load from load_superbursts_polygons()

Returns
superbursts1_polyPolygon
superbursts2_polyPolygon
Other Parameters
labelbool

whether to add the label ‘superbursts(1/2)’
