Helio's latest activity
-
Helio replied to the thread Exoplanet Stats.Yes. Obeservational bias has been a given from day one. Confirmation requires observations for three orbits, so more distant exos will... -
Helio replied to the thread Question How to get started with Astronomy?.Welcome aboard, Mason. You're off to a good start coming here. You can use the search tool to find information on a huge range of...
-
Helio replied to the thread Exoplanet Stats.Here is a 4-exo system table. I've added the star type, when given, and replaced the unknown mass exoplanets with "?", but the color...
-
Helio replied to the thread A super-Earth beyond Mars would have made Earth nearly uninhabitable.I've posted in Exoplanet Stats a table for one set of multi-systems.
-
Helio replied to the thread Exoplanet Stats.You're welcome. I find Excel VBA coding more fun than assembling jig-saw puzzles. So, here's some colorful fodder to consider. The...

Helio replied to the thread A super-Earth beyond Mars would have made Earth nearly uninhabitable.Rod, If seems you’re very right in seeing the solar system as more unique. Look at the list as linked to in post 14. The solar system...
-
Helio replied to the thread Exoplanet Stats.Ok. I knew there was a bigger picture to look at, but I was able to establish the above size-distance order so I decided to toss it in...
-
Helio replied to the thread A super-Earth beyond Mars would have made Earth nearly uninhabitable.I've come up with something in my limited kit of magical programing tricks, but I thought the Exoplanet Stats might be the better place...
-
Helio replied to the thread Exoplanet Stats.Per Unclear Engineer's ideas here, I have managed to gather some information that may be helpful. Of the 7300 exoplanets, there are a...

Helio replied to the thread A super-Earth beyond Mars would have made Earth nearly uninhabitable.Sounds interesting. To determine if an exo is “rocky” we can set an orbital range. Using solar equivalent distances, perhaps 0.1 to 3...

Helio replied to the thread A super-Earth beyond Mars would have made Earth nearly uninhabitable.I had limited time so I took some short cuts for now. The M class likely has smaller planets, I think. The K, F, and G-class have many...
-
Helio replied to the thread A super-Earth beyond Mars would have made Earth nearly uninhabitable.Here is a quick table showing M-class systems. The Solar Equivalent distance is calculated. The bright green highlight are the exos...

Helio replied to the thread A super-Earth beyond Mars would have made Earth nearly uninhabitable.That shouldn't take much programing. I'll have time tomorrow, hopefully.
-
Helio replied to the thread A super-Earth beyond Mars would have made Earth nearly uninhabitable.I can’t do a graphic, but I can do a table. Just define what table you want, if any.

Helio replied to the thread A super-Earth beyond Mars would have made Earth nearly uninhabitable.The giants are formed past the Frost Line, where gas density is much higher in ice form, as I understand it. The protonsun was about...
