巨星のまばたきを聴く――197kmの電波干渉計が見た、ミュー・ケフェイの素顔 — 画像プロンプト

1. ポンチ絵（概要図）

用途：記事本文・note下書きの「197kmの仮想望遠鏡」節に埋め込み、KNIFE干渉計の仕組みを1枚で理解させる図解 ファイル名：mu-cephei-sio-maser-diagram.webp

Clean flat infographic diagram, minimal text. Two radio telescope dishes on a stylized map of Japan, one labeled dish at “Kashima” (34m) and one at “Nobeyama” (45m), connected by a single glowing dashed baseline arc labeled with a distance mark, 197km apart. Both dishes point upward toward a single red star icon in the sky. A subtle annotation shows the two dishes’ signals combining into one large virtual telescope aperture circle, larger than either physical dish, hovering between them. High-contrast dark-blue background, thin glowing cyan/white lines, technical-diagram aesthetic like a science magazine explainer, no dense paragraphs of text — at most 2-3 short labels.

2. ヒーロー画像（近未来・かっこいい科学イメージ）

用途：記事冒頭のリード画像／note下書きの「13人の共著者」節（三好真の後年の活躍を予感させる段落の直前）に挿入／将来的にYouTubeサムネイル・Suno楽曲カバーの元絵にも流用 ファイル名：mu-cephei-sio-maser-hero.webp

Cinematic near-future space art, no text. A massive red supergiant star (garnet-red, M-type, glowing with turbulent surface convection) dominates the upper half of the frame. Around the star, at a small distance from its surface, several bright pinpoint light sources pulse in warm orange-white — these are maser hot spots, rendered as tiny brilliant sparks connected by faint concentric rings suggesting radio-wave interferometry. In the lower foreground, a faint ghostly overlay of two radio dish silhouettes on distant hills, aimed at the star, connected by a thin glowing data-link line stretching across a dark landscape toward the star. Deep space background with subtle nebula color grading (crimson, amber, deep indigo). Atmospheric, epic scale, high production-value sci-fi illustration quality, thumbnail-safe focal point (the star and its maser points read clearly even at small size).
