I'm not an expert on Moebius, I'm afraid, but a little search on the net has led to some dates.
You've listed most of the names in French, so I am assuming that you want the dates that they were published in "Metal Hurlant", as opposed to the English-language "Heavy Metal".
Most of these come from the bdoubliees.com
site and it is a fairly reliable source, though I am not accepting responsibility for any errors.
I've included the original dates of publication as best I can. Where I have a (?) is a warning because I am not sure of the source so I advise caution (see my notes further down). I've also included the correct spelling of some of these titles.
- Double Evasion - 1980
- Le Major Grubert - 1975(?)
- Paradise Nine's Strange Flowers - 1978(?)
- Une Planche - 1976
- Ktulu - 1978
- Tueur à Gages (correct to "Tueur à gage") - 1978
- Vous faites l'objet de ceci et de cela - 1974(?)
- Split ("Split le petit pionnier de l’espace") - 1975
- Y'a pas moyens - 1972
- Musique ininterromque (correct to "Petit programme de musique ininterrompue") - 1973
- Rock City - 1979
- Approcher sur Centauri - 1975
- Variation n. 4070 ("Variation No 4070 sur 'le' thème") - 1978
"Le Major Grubert" was actually a series rather than a one-off story. Dates of publication can be found on his bdoubliees.com entry
This entry in comicvine
indicates that "Paradise Nine's Strange Flowers" was published in the April 1978 issue of "Heavy Metal". I cannot be certain if it was published in French around the same period.
This bedetheque.com comment
suggests that "Vous faites l'objet de ceci et de cela" was first published in 1974.
Another BDoubliee.com page
indicates that "Y'a pas moyens" was published in Pilote magazine in 1972 and that "Petit programme de musique ininterrompue" was published in 1973. These were under his other pen-name of Gir.
Good luck with your chronology.Note to moderators:
the links that I have provided here are mainly of listings of publication titles. The covers of magazines that are included in these sites come under the "fair use" notion and can hardly be seen as copyright breaching.Moderator Note:
