如何在 tikzpicture 中将一个节点的标签包装成两个？

Question

我想要得到下图，但不知何故我无法划分节点的标签。我使用的代码如下。

代码：

\documentclass[12pt,english]{article}
\usepackage{graphicx}
\usepackage{tikz}
\usetikzlibrary{calc}
\usetikzlibrary{patterns, arrows.meta}
\usetikzlibrary{patterns,math}
\usetikzlibrary{arrows}
\usetikzlibrary{shapes.geometric}
\usetikzlibrary{arrows,decorations.markings}

\begin{figure}[H]
\begin{center}
\begin{tikzpicture}
\begin{scope}[every node/.style={draw, circle, inner sep=0pt, minimum size=.15cm, fill=black}]

  \node[label=above:\text{$a=w_{2}$}]       (B) at (1.5,1.5) {};
  \node[label=above:\text{$w_{3}$}]         (C) at (3,1.5) {};
  \node[label=below:\text{$k=w_{p}$}]       (D) at (1.5,-1.5) {};
