Soft Equations of State

(This erasure/collage poem was written by deleting most of the words in the article, “Soft equations of state for neutron-star matter ruled out by EXO 0748-676,” written by Feryal Özel in Nature, 29 June 2006. The words in this poem were taken from their article in this exact order. No words not found in the article were added. I created the accompanying collage with images from several issues of Nature as well.)

The interior of stars matter.
That the early universe achieved
terrestrial matter appears to rule
out soft equations and unconfined
centres.

The radiation flux,
the stellar surface observed
from a single source is color,
temperature, expressions, yield—
the stellar parameters.

Tighten these constraints,
the slowly spinning stars,
rotational infinity, a fitting function.

The main uncertainty bursts,
dynamically unimportant flash.

Shown are the contours,
the black shaded area.

Uncertainties, uncertainties
limit the actual radius of the star.

Freefall, time scales!

Unknown binary system
affects the X.

I can obtain lower limits
as a strange star.

Only the stiffest equations of state
in a small orbit are negligible.

My method is a direct source,
a globular cluster.

The mass and radius of stars
are excluded by my self-bound,
bare, strange matter.

Stars, I therefore argue,
represent the ground.
