An astronomer is a scientist in the field of astronomy who concentrates their studies on a specific question or field outside the scope of Earth.
The astronomical unit (symbol: au, ua, or AU) is a unit of length, roughly the distance from Earth to the Sun.
Brown dwarfs are substellar objects that occupy the mass range between the heaviest gas giant planets and the lightest stars, having masses between approximately 13 to 75–80 times that of Jupiter, or approximately to about.

The light-year is a unit of length used to express astronomical distances and measures about 9.5 trillion kilometres or 5.9 trillion miles.
A molecular cloud, sometimes called a stellar nursery (if star formation is occurring within), is a type of interstellar cloud, the density and size of which permit the formation of molecules, most commonly molecular hydrogen (H2).
New Year is the time or day at which a new calendar year begins and the calendar's year count increments by one.
New Year's Day, also called simply New Year's or New Year, is observed on January 1, the first day of the year on the modern Gregorian calendar as well as the Julian calendar.

OGLE-TR-111 is a yellow dwarf star approximately 5,000 light-years away in the constellation of Carina (the Keel).
Photometry is a technique of astronomy concerned with measuring the flux, or intensity of an astronomical object's electromagnetic radiation.
A protoplanetary disk is a rotating circumstellar disk of dense gas and dust surrounding a young newly formed star, a T Tauri star, or Herbig Ae/Be star.
Spain (España), officially the Kingdom of Spain (Reino de España), is a sovereign state mostly located on the Iberian Peninsula in Europe.
Spectroscopy is the study of the interaction between matter and electromagnetic radiation.
A star is type of astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.
A star catalogue (Commonwealth English) or star catalog (American English), is an astronomical catalogue that lists stars.
In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
Tenerife is the largest and most populated island of the seven Canary Islands.
The Tycho-2 Catalogue is an astronomical catalogue of more than 2.5 million of the brightest stars.
