4. NARIT’s Key Sciences
1. Impact from Space: The first key science deals with investigating how
space weather affects the upper atmosphere, as well as how the upper
atmosphere affects the lower atmosphere and vice versa. It also aims to
study the effect of man on earth’s climate.
2. Understanding Physics of the Universe: The key science comprises
several fields in stellar physics, including the study of the extremes of the
Universe (i.e. gamma ray burst, compact objects) and the study of stellar
evolutionary process. A few highlighted research topics in this key
science are: variable stars and binary systems, star formation, and stellar
population study.
3. Exoplanets and Astrobiology: The key science focuses on the search for
new exoplanets using various observational techniques, the study of the
physical properties of exoplanets and the understanding of planetary
formation, the exploration of the earth-like exoplanets with habitable
zone and clues of lives outside the Solar system.
4. Understanding the Origin of the Cosmos: The key science focuses on
the key questions of modern cosmology and physics: What causes the
late-time accelerated expansion of the Universe? What is the Dark
Matter? And how do the large-scale structures (e.g. galaxies, groups and
clusters of galaxies) form and evolve?

15. Astronomyand Atmospheric
Science inthe PolarRegion

16. Astronomy at Polar Region
Polar region (Arctic/Antarctic Plateau) is
a perfect place for astronomical observations
due to its
- Long and continuous 6 months dark clear
winter sky
- Stable atmospheric condition with
excellent sky seeing
We can do the long-term, unbroken and
continuous monitoring of various types of
celestial objects eg: binary stars, variable
stars, exoplanets, transient phenomena,
exploding stars ect. Also the investigations of
the aurora phenomena on earth.

21. Collaboration with East Asian Observatory
(EAO)
21
NARIT, as the IAU Southeast Asia Regional
Office of Astronomy for Development, has
been invited as one of the member institutes
of the EAO. NARIT is now working in
collaboration with EAO under an the
Memorandum of Agreement between the 2
institutes (September 2017). The EAO
currently operates the James Clerk Maxwell
Telescope (JCMT), which is the largest
single dish telescope to operate at
submillimeter wavelengths. The 15-meter
telescope is located on the summit of Mauna
Kea in Hawaii. The EAO operates the JCMT
on behalf of the University of Hawaii since
1st March 2015.

22. Terahertz Astronomy
22
We are interested in using the Terahertz (THz)
observations of interstellar atoms, molecules,
and dust serve as powerful probes of the
conditions within the interstellar medium that
permeates newly formed distant galaxies in
the early universe which can be well detected
in terahertz frequencies.

23. The Study on Close Binary Systems
Evolutionary stages of close binary
systems can be study through different
classes:
• Detached binaries
• Semi-detached binaries
• Contact binaries
• Low mass ratio deep contact
binaries
• Binary mergers: Such binary
mergers are likely to be
responsible for many eruptive
events in the Galaxy (e.g., V838
Mon; Tylenda & Soker 2006)
• Luminous Red Novae (LRN)

24. Search for the progenitor of LRNs by AST3-1
 Yunnan Observatories and NARIT has
long been cooperated on the research of
eclipsing binary stars
 AST3-1 is the second-generation wide
field optical photometric telescope at
Dome A
 285 eclipsing binaries (including EW,
EB, and EA-types) were observed in the
Galactic Disk (e.g., Wang et al. 2017)
 Search for the progenitors of LRNe
(deep and low-mass ratio contact
systems).

25. It is discovered that AST7302 is a contact
binary with the lowest mass ratio 0.067
• i=15.38 mag.
• P=0.37218 days
• T1=5400 K
• i = 75.5
• f = 13.0 %
• q=0.067
They are the progenitor candidates of Luminous red
novae
