TL;DR: Thái Âm is a Water-element star representing the moon, gentleness, emotion, and the mother figure; like Thái Dương, its influence shifts sharply with dignity and speaks especially strongly to women's fortunes.
What does the name Thái Âm mean?
Thái Âm (太陰) means "the moon", a principal star of the Water element carrying pure Yin polarity, standing opposite and complementary to Thái Dương in the "Sun-Moon" pair. Where Thái Dương represents daylight, career, and the father, Thái Âm represents the gentle glow of night, inner emotional life, and the mother. In East Asian culture the moon is also tied to womanhood, fertility, and cycles, so Thái Âm additionally represents the fortune and health of the women in the native's family.

What is Thái Âm's core nature in the Tân Biên tradition?
The Tân Biên text describes a native with Thái Âm ruling the Life Palace as refined in appearance, with smooth skin, and a gentle, sensitive temperament rich in feeling and intuition. They live an inward life, are considerate of others, possess aesthetic taste, and often succeed in the arts, caregiving, education, or work demanding meticulous patience. Thái Âm's weakness is a tendency toward melancholy and worry, indecision in moments calling for decisive action, and a withdrawn nature easily wounded by others' words. As the folk saying goes, Thái Âm is like "the full-moon light of the fifteenth night", beautiful and gentle, yet forever cycling between fullness and waning, mirroring the emotional ups and downs typical of this star's natives.
What does Thái Âm mean by dignity?
Thái Âm is strongly shaped by birth hour, similarly to Thái Dương but in reverse. It is exalted (miếu) at Dậu, Tuất, and Hợi (evening and night), the moon at its fullest, bringing rich emotional fulfillment and abundant wealth, especially favorable for those born at night. It is prosperous (vượng) at Tý, and favorable (đắc) at Thân. Conversely, Thái Âm falls weak (hãm) at Thìn, Tỵ, and Ngọ (midday), its light dims, bringing emotional setbacks and a harder path for the health or fortune of the native's mother or wife, while the native themselves may grow melancholic and lack confidence. Someone with a weak Thái Âm should work to balance their emotions and avoid bottling up feelings for too long, as it can take a toll on mental health.
What does Thái Âm mean in key palaces?
In the Life Palace (Mệnh): whether male or female, the native carries a gentle, refined temperament, perceptive and empathetic toward others. When exalted, this is someone with quiet charisma, well-liked by many; when weak, they may withdraw and become overly sensitive.
In the Wealth Palace (Tài Bạch): Thái Âm favors wealth built quietly and gradually, often tied to real estate, savings, or steady long-term income rather than sudden riches. An exalted placement here usually indicates strong personal financial management, especially for women.
In the Marriage Palace (Phu Thê): for a male chart, Thái Âm here typically points to a gentle, attentive wife skilled at nurturing the family; when exalted, the marriage tends to be fulfilling with a virtuous, capable spouse. For a female chart, this star colors the relationship with the mother-in-law or the native's own inner emotional life.
In the Property Palace (Điền Trạch): Thái Âm carries particular weight here, as it governs housing and land, an exalted placement often signals substantial, stable real estate holdings.
What are notable star combinations with Thái Âm?
As noted under Thái Dương, the "Sun and Moon Shining Together" pattern, when both stars are exalted, is a rare and highly auspicious configuration. Thái Âm paired with Thiên Đồng ("Đồng Âm") produces a gentle, easygoing temperament, commonly seen within the broader Cơ Nguyệt Đồng Lương pattern. Thái Âm paired with Xương Khúc adds artistic and literary flair; paired with Kình/Đà or Hỏa/Linh, it tends to deepen emotional melancholy and hardship.
