Shri Gopalakrishna Rao (Meena) had done initial major contribution to the stellar astrology. He has subdivided all the 27 stars into 243 portions to indicate Kaalamsa positions of a star. Then Shri KS Krishnamurthy further went ahead on this and invented a new concept called Sublord theory (KP astrology). Based on his theory all 12 bhava positions are subdivided into 249 sublord positions. Extending the Shri KS Krishnamurthy theory, Thilak K. Baskaran introduced the cuspal interlinks concepts for the astrological analysis and it is called as Krishnamurthy-Baskaran System or KB astrology.
The core theory of Baskara Astrology is based on the principle, the star lord shows the event and the sub lord determines whether that event is favorable or unfavorable.
In Baskara astrology, if the cuspal sublord of any bhava has interlinks with the 1, 2, 3, 5, 9, and 11th bahvas to its position would always yield favorable results. Whereas with the 6 and 7th bhavas linkage to the position of concerned bhava would yield favorable results moderately. With the linkage of 4, 8, 10 and 12th bhavas to the concerned bhavas would always yield unfavorable results.
Stellarastrolog.in web application uses the KB system for the analysis.
Stellar astrology is an advancement of the vedic astrology. In astrology the 360° zodiac belt is divided into 12 zodiacs signs of each 30°. Similarly the 360° zodiac belt is divided as 27 star divisions of each 13° 20′. Further each star division 13° 20′ is divided into 4 equal parts of each 3° 20 which is known as padas. Hence each zodiac sign has 9 padas. Check zodiac division post more about this.
Vedic astrology, which is used during an Astrology Character Reading Consultation Session, the astrological interpretation is restricted based on the placement of the planet in the zodiac sign, whereas in stellar astrology the interpretation is based on the star/constellation in which the planet is placed within the zodiac sign. For example, if a planet is in Aries sign then there is chance that it can be in any one of the three constellations Ashwini, Bharani or Krittika, so the planet performs the actions differently according to which constellation it is deposited.
Each constellation is owned by a planet and it is called as star lord. Further each constellation is divided into 9 parts and each part is owned by the planet which is called as sub lord. Stellar astrology uses Placidus system of house division and explores to the level of sub lords with respect to the planet position status in the zodiac. In stellar astrology, the astrological analysis is done by considering the star and sub lords and the inter-links among them with respect to the sign they occupied. Thus stellar astrology is systematic and very well defined for accurate astrological analysis.
As the time is divided into hours, minutes, seconds, milliseconds, … the zodiac is also divided into an hierarchical divisions. The initial level zodiac division is 12 parts each denoted as zodiac signs of 30°. For each zodiac sign, a planet is assigned as a sign lord. Except Sun and Moon, other seven planets get ownership of two zodiac signs. For example Mars is the sign lord of Aries and Scorpio. The astrological significant nine planets is taken into further levels of divisions. The entire zodiac is divided into 27 (9 x 3) divisions and it is called nakshatra divisions. Similar to the sign, each nakshatra has ownership lord which will be one of the nine planets, it is called as Star Lord. For example, Ketu is the star lord for Ashwini, Maga and Mula nakshatras. Further each nakshatra is divided into 9 parts as per Vimshottari Dasha period length and each part is owned by a planet which is called as Sub Lord. Again, Sub Lord portion is divided in a similar fashion into 9 parts denoting Sub-Sub Lord.
For better understanding, the following figure shows how the Aries sign is divided as star and sub lords. In similar fashion the other signs in the zodiac belt is divided.
Similar to the time accuracy like 11:30:34 145 (11 hour, 30 minutes, 34 seconds, 145 milliseconds), the astrological accuracy is done as Sign Lord, Star Lord, Sub Lord, Sub-Sub Lord for the given zodiac point. For example, the zodiac point 6° 50′ 53” can be astrologically represented as Mars (Aries – Sign Lord), Ketu (Ashwini – Star Lord), Rahu (Sub Lord), Venus (Sub-Sub Lord). This approach helps in distinguishing the twin births cases and other ambiguities in the astrological calculation.
