The discovery that there are parallel pathways for vision was made : one classic rod-and cone-based arising from the outer retina, the other a rudimentary visual brightness detector arising from the inner retina.

A variability of the visual brightness was also detected which could fit to 7.9 h or 15.8 h rotational period ( the distinction between single or double-peaked curved could not be made with confidence ).

Wray 17-96 has an absolute bolometric magnitude of & minus; 10.9 ( 1.8 million solar units ), making it one of the interstellar extinction and the visual brightness is reduced by nearly 9 magnitudes.
24.
Because of the high temperature, it emits most of its energy in the ultraviolet region of the electromagnetic spectrum, and the visual brightness is only 87, 000 times the sun ( M V & minus; 7.52 ).
25.
The variations in infrared brightness compared to visual brightness correspond quite well to the light curve, suggesting that brightness changes are related to colour or extinction changes, but there has been a secular trend in the B-V colour index.
26.
This shows that there are two pathways for sight in the retina one based on classic photoreceptors ( rods and cones ) and the other, newly discovered, based on photo-receptive ganglion cells which act as rudimentary visual brightness detectors.
27.
Because relatively more infrared radiation is produced when the star is cooler, the maximum brightness in the infrared occurs when the visual brightness is already decreasing, and the maximum bolometric luminosity occurs at around phase 0.25 around halfway from maximum to minimum visual brightness.

It was discovered that there are parallel pathways for vision one classic rod and cone-based pathway arising from the outer retina, and the other a rudimentary visual brightness detector pathway arising from the inner retina, which seems to be activated by light before the other.
