I found solution, May this can help you in future.
$author = Author::create([
'author_type_id' => $request->author_id,
]);
$post = Post::create([
"post_type_id" => $request->post_type_id,
"author_id" => $author->id,
"author_type_id" => $request->author_type_id,
"article" => $request->article,
]);
Auther::create([
'author_type_id' => $request->author_id,
]);
