couple of stipulations. We agree not to engage in hostile actions against them or any other races we may find there, and also that we accept their terms for future trade negotiations with them. But from what George Jones has told us, thereâs no one there whom weâd consider to be an enemy, and all they want from us is the same thing that they want from everyone else... raw materials like iron, copper, zinc, silicon, and so forth.â
âI see.â Andromeda slowly nodded. âAnd I take it that weâve been given the planetâs coordinates along with the starbridge key.â
âThe key, we have. George Jones said that the coordinates will be given to us once one of our ships makes the jump.â Harker frowned slightly. âAnd thatâs something of a puzzle right there. Because, according to our data, thereâs not a lot in the danui home system, let alone planets habitable by us or anyone else.â
He looked at his datapad again. âDisplay HD 76700 system diagram,â he said loudly, and George Jones vanished, to be replaced by a three-dimensional schematic of a solar system. It was remarkably simple: a midsized star, with a single planet in a close yet highly elliptical orbit around it.
âHD 76700,â Harker continued, reading from his padâs screen. âType G6V star, same spectral class as 47 Uma but just a little larger, located 214.9 light-years from Coyote.â He pointed to the sole planet circling the star. âIn the early twenty-first century, optical inferometry found a small gas giant in close orbit around it. Since its semimajor axis is a little less than .05 AUs, that means HD 76700-B completes an orbit of its primary about once every four days.â
Andromeda nodded. Hot Jupiters, while freakish, were not uncommon in the galaxy. They were usually gas giants that evolved in the outer reaches of a solar system, only to have their orbits gradually deteriorate over time. When that happened, the planets began long, slow falls toward their primaries, death spirals that took millennia to complete.
âAre you sure youâve got the right system?â she asked. âI mean... look, Iâm not an astronomer, but even I know that habitable worlds of any kind arenât usually found in the same system as a hot jupe. The whole system gets destabilized.â
âOur people thought of that, too,â Harker said, âbut the danui insist that this is their home system and that more than one habitable world exists there. But itâs still strange as hell... Overlay HD 76700 remote image.â
On top of the schematic diagram, a two-dimensional photographic image was transposed: the danui star, a small white blob brighter than the tiny dots of light in the background yet surrounded by a nimbus the color of verdigris on rusting copper pipes.
âThatâs what we see when we point a telescope at their system,â Harker said. âWe see their star, all right, and although HD 76700-B is too small to be seen directly, we know its there because of the gravitational effect it has on its primary. But if thereâs a planet located within a 1-AU radius, we canât make it out because of this thingââhe pointed to the nimbusââwhich appears to be some sort of dust cloud or planetary nebula.â
âA dust cloud?â Andromeda peered closely at the image. âWithin 1 AU? Wouldnât that make any planets within the system... ?â
âUninhabitable?â Harker finished. âYes, at least thatâs what the science boys at the university told me when I checked with them.â He paused. âBut if thereâs no habitable planet anywhere in the system, why would the danui tell us otherwise? The nord , too, for that matter.â
Andromeda absently tapped a forefinger against her lips. âI think I know where this is going,â she said at last. âWeâve been given an awfully
