A story that is the story of our failure to make a story, can only be told in terms of heroes & monsters.

Hercolubus 


(via space dot com)

So Proxima has a planet... Also known as Gliese 551 & HIP 70890, this dim red flare star (according to the paper, visual magnitude 11.05 at 1.295 parsecs--for a parallax of "0.7722, although Hipparcos gives 0.77233--), which is probably (but not certainly?) coeval with Alpha Centauri, with spectral type M5.5 V (3054 K), stellar mass 0.118 ⊙ (2/17) and observed radius 0.1410 (or 1/7th ⊙), appears to have a planet of at least 1.27 (about 52/41) ⊕ in a close, 11.186 (1/33 y.)-day orbit.

This works out to 0.048011508 or 1/21 AU, which for a visual luminosity of 0.00005553162797 (1/18008) & bolometric (BC at -3.60) 0.001528278072 (1/654), makes for a blackbody temperature of 252.3673234 of the planet. If its albedo & greenhouse effect are like the Earth's (0.36, 38K) then its average surface temperature is -9° C; if a little larger (say, 0.60 & 80), an average of 8° C is possible.


According to Li Zeng, a rocky planet with this mass should be about 1.083159015 (13/12) ⊕ in diameter (=8576 miles), & have a surface gravity of 1.083247851 ⊕ (at about the same density; a greater density is possible).

I call it "Hercolubus" because a cloud covered world of a star this cool would be red to our eyes. (Its inhabitants might be Hercolubozos.) --Certainly not Ad Astra or Furon...or even Meton. Discussions of its potential climates.

Though much has been said about this "red" sun, it is much bluer than candlelight (1400K); its energy is about 53% of our sun's & i would expect a leaf running on the same chemistry to be about twice as large as its Terran equivalent. Illumination-wise, the day would seem about 2% of ours (2/83), or about the same as a point in orbit between Jupiter & Saturn--brighter than "Pluto Time," at any rate.

Clocks are supreme on Hercolubus.

"...I asked how can you ever be sure
that what you write is really
any good at all and he said you can't

you can't you can never be sure
you die without knowing
whether anything you wrote was any good
if you have to be sure don't write"

--W S Merwin

"Paul Oppenheimer writes that the sonnet, developed by a twelfth-century lawyer out of a folk song form, helped develop the modern idea of the isolated, three-dimensional and self-sufficient self. What might it mean about the twenty-first century idea of self that we are so increasingly captivated by the villanelle?" --Annie Finch

"My understanding of this budding genre “hardvapour” is it’s the Trans-Siberian Railway deportation of vaporwave from Pacific Asian culture, transferring to a bus that breaks down, on foot finding a city where illicit activity reigns anarchy supreme, and creating a chem lab is the only viable “next step.” Maybe you’re in Georgia, too. Or Mykolaiv. Obviously, this chem lab is created in an abandoned factory basement, where people host violent parties with their shirts off, while the night is fueled by krokodil, vodka, and koke. Marked by heavy bass, hard industrial tinge, and atmospheric rave melodies, “hardvapour” musically functions either in the realm of flinging fists or neck-snapping head-nods. Not to mention a variety of “WARNING” samples, claiming the music being fronted is potentially hazardous to the listener’s health, as if radiation or contaminant will emit from headphones/speakers. Shit, and the culture itself stems from grainy cemented surveillance visuals, menacingly broken English, and threatening the sale of Blu-ray DVD player for CC number (including the three-digit code on back of card, please). So you find room in that chem lab so the new label AntiFur can move in." --C Monster

"This also returned me to one of my favoured go-to analogies for the current situation, namely, civilization as the post-impact Titanic. In a comforting manner I’ve reminded myself that the EU referendum probably amounts to little more than a rearrangement of the deckchairs or orchestral music on the sinking Titanic, or, perhaps more accurately, it is a change with regard to where and with whom one stands. But there is little point rocking the boat when the boat is already sinking. As to whether we are nearer the aft, the stern, the lifeboats, or how much time we have left, all that we can know with much confidence is that the ship will sink. The only meaningful thing that we have any significant control over is how we behave towards one another as it goes down!" --Pagan Metaphysics blog

"jetztzeit- Walter Benjamin uses this term in his ‘Theses on the Philosophy of History’ to describe a notion of time that is ripe with revolutionary possibility, time that has been detached from the continuum of history. ...Benjamin contrasts jetztzeit with the ‘homogeneous empty time’ of the ruling class, which is history written from the perspective of the victors..." --Oxford reference

Apishal 


(pic by Lanny Quarles on Facebook)

Wolf 1061 (=prime), AKA Gliese 628, Vyssotsky 164, HIP 80824, & BD-12° 4523 (oldstyle)(4523 is also prime), in Ophiuchus, has been discovered (as of 12/15) to have 3 terrestrial-type planets in close-in orbits. Located at a distance of 14.0 light years, this is presently the closest prospect for an earthlike exoplanet. (It goes between #5 & #6 on this list.)

Parallax is given as 0."23451 (Hipparcos) or 0."23298 (I use); apparent magnitude 10.1 (I use Hipparcos’s 10.0278), which gives a visual luminosity of 0.001607607232 ⊙. The spectral type is variously given as M3-3.5 V & M4. It is listed on Simbad as a BY Dra variable (=V2306 Oph)--this is also the source of the other parallax. I find that using M2.5, with T= 3280K (3393 is given) & BC= -1.71, giving a total luminosity of 0.007765688238, is closest to the 0.00787 which is given. This star appears to be somewhat hotter & less massive than usual for its brightness.)

The planets have periods of 4.8876, 17.867, & 67.274 days. If the star’s mass is 0.25 (I would give it at least 0.30--if the star's mass is higher, a planet's average temperature for the same orbital period would be colder), then the middle planet’s semimajor axis comes to 0.084258922 (= 1/12) AU. (Note that its eccentricity is considerable: 0.19.) Its resultant blackbody temperature is 286.0K. Not a lot higher than Earth’s 279K, but the average temperature for synchronous rotation is more like 40% higher, with temperatures around the globe varying according to both the distance from the subsolar point, & the orientation of local winds (which are bound to be considerable). Apparent size of this red sun would be 3.27 ⊙. The blackbody at periastron 0.068249726 AU is 317.8K & at apastron 0.100268117 it is 262.2, so it varies ± 27.8K.

All in all, an almost perfect equivalent to the (probably mythical) "ribbon-world" Zarmina. (Although i am now seeing the term "eyeball earth" more often.)

Synodic periods of b & d relative to c would be 6.73 & 24.33 days, respectively. If the radius is 1.64 ⊕, surface gravity would be 1.58 ⊕ if 1.60 (by another formula), it would be more like 1.9⊕. With such gravity, i would expect not bipeds but tripeds or quadrupeds as the dominant species... The star does not appear in fiction, except for the video game Traveller, where a planet is named "Apishal" (in the same game, Ross 47 is Remulak--home planet of the Coneheads). I like the names Audelia, Claymore, Antobia here...
