There may not be, but it's easily created, since there is a prefix that indicates non-existence: a-. So it'd be abaric.
On the minus side, airless is much more straightforward to pretty much everyone.

Abaric sounds cool and follows the pattern. Airless is more straightforward. I would rather have abaric but that's probably only because I know what it means.There may not be, but it's easily created, since there is a prefix that indicates non-existence: a-. So it'd be abaric.

Say, shouldn't the "airless" bit be omitted from asteroids? All asteroids are airless; they're too small to retain atmospheres. When they do have volatiles around them, they become comets.
Arid seems the best one imo
...what?
...am I missing something?Wikipedia:
Like Earth, Mars has differentiated into a dense metallic core overlaid by less dense materials. Current models of its interior imply a core with a radius of about 1,794 ± 65 kilometers (1,115 ± 40 mi), consisting primarily of iron and nickel with about 16–17% sulfur.
They all are already in SE, though not separated to a special classes. Because they have nothing special:
They are just a very hot neptunes/jupiters which are lost their hydrogen or even helium. SE generating those.
Are you confused it with chthonian? Sudarsky III class is a warm gas giants.
Why we should consider a planets with non-motlten or missing core as a separate class? What is so special in their nature? SE generates the bulk composition now, so you can see the core mass in the Wiki. It could be as low as 1%. By the way, Earth have a solid iron core.
They are corresponding to the cold, temperate, warm, hot and torrid jupiters (gas giants), respectively. SE already considering theoretical appearance of gas giants at different temperatures to generate their textures.
I think a planet without a core has no magnetic field.
This is a common misconception. Magnetic field does not protect the surface directly. The air itself protect - the radiation level at 20 km altitude is negligible. A thin layer of water or ice, just few centimeters, protects against solar and cosmic rays by 100%. Life under ice or in the water is 100% protected without any magnetic field. What magnetic field is doing, is protecting atmosphere at some degree against non-thermal dissipation. The dissipation speed depends on many factors, not only on radiation or solar wind. Magnetic field plays zero role in evolution of atmosphere on planets near a silent stars, but can be important near red dwarfs, whose flares ripping apart planetary atmosphere by non-thermal mechanism. Great example is Venus - it have no magnetic field, closer to Sun and smaller than Earth, but its atmosphere is enormous. Mars lost its atmosphere simply due to a weak gravity.
