Tiåmåt

A slow, eccentric passage

Tiåmåt follows a circumbinary orbit around Takbiru, a red supergiant, and Takmat, its white-dwarf companion. The orbit has a semimajor axis of about 324 AU and eccentricity 0.20.

The spin axis remains tilted by 40° in a fixed direction. Southern solstice occurs at periastron; northern solstice at apastron. Orbital motion speeds up near periastron.

A surviving sea separates two continents, while falling waters have exposed a natural land corridor on the opposite side. Inland seas and rivers persist across the continental interiors. The northern ice cap gives way to the temperate lands of the Hakbiru. The south retains little polar ice and some temperate terrain; farther toward the equator, dry landscapes dominate.

This is an artistic, physically informed visualization. Planet and star sizes are enlarged; stellar brightness is compressed. In Orbital view, the binary is visually expanded so the red supergiant and white dwarf remain distinct; their displayed sizes and separation are not to scale. Terrain and sea placement are imagined, not a canonical map. Rotation is accelerated independently of the orbital clock. The galactic band is an artistic background.
