Nepal does not have a well-known nuclear physics program compared to some other countries, but there are a few institutions and individuals in Nepal who are engaged in research and education in nuclear physics and related fields. The study of nuclear physics in Nepal primarily involves activities related to radiation detection, the application of nuclear science in medicine (such as radiation therapy), and the use of nuclear techniques in agriculture and industry.

A Wolf-Rayet nebula is a type of nebula associated with Wolf-Rayet stars, which are hot, massive stars in a late stage of stellar evolution. These stars are characterized by strong stellar winds and high temperatures, leading to significant mass loss. The material expelled from these stars interacts with the surrounding interstellar medium, creating distinctive nebulous structures. Wolf-Rayet nebulae are often observed in the context of massive star-forming regions or the remnants of supernova explosions.
A variable nebula is a type of astronomical object that exhibits changes in brightness or appearance over time due to various factors, including the motion of material within the nebula or changes in the illumination by nearby stars. These nebulas are often associated with young stars and can be composed of gas and dust.
A supernova remnant is the structure resulting from the explosion of a star in a supernova event. When a massive star exhausts its nuclear fuel, it undergoes gravitational collapse followed by a catastrophic explosion, ejecting the outer layers of the star into space at high velocities. This explosion not only disperses a vast amount of stellar material, but it also generates intense shock waves that propagate through the surrounding interstellar medium.
Sh2-308, also known as the "Dragon Nebula," is an emission nebula located in the constellation Monoceros, the Unicorn. It is part of a larger region of star formation and is noted for being a site of active stellar birth. Sh2-308 is associated with the open star cluster NGC 2244, which is a young cluster of stars that has formed from the surrounding gas and dust.
A reflection nebula is a type of nebula that does not emit its own light but instead reflects the light of nearby stars. These nebulae are often composed of dust and gas, which scatter the light from nearby luminous stars, making them visible. Reflection nebulae tend to appear blue because blue light is scattered more effectively than red light by the small particles in the dust.
A pulsar wind nebula (PWN) is a type of astronomical nebula formed by the wind of particles emitted from a rotating neutron star, known as a pulsar. Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation out of their magnetic poles. As the pulsar rotates, these beams sweep across space, and when they are pointed towards Earth, they are detected as pulses of radiation, hence the name "pulsar.
Nebulium is an outdated term that was historically used to refer to a hypothetical element believed to exist in the nebulae, particularly in the context of early astrophysical studies. The concept emerged in the late 19th century when scientists were trying to understand the spectral lines observed in certain nebular emissions, especially those that did not correlate with known elements at the time.
NGC 6326 is a planetary nebula located in the constellation of Ara. It is known for its complex structure and bright appearance, which is typical of many planetary nebulae. NGC 6326 is a region of ionized gas that has been expelled from a dying star, which in this case is a post-main-sequence star that has shed its outer layers.
NGC 2078 is a star cluster located in the Large Magellanic Cloud (LMC), which is a satellite galaxy of the Milky Way. This open cluster is situated in the constellation Dorado and is part of the rich star-forming region of the LMC. NGC 2078 is notable for its stars, many of which are relatively young, and it has been studied for insights into stellar evolution and the dynamics of star clusters.
An interstellar cloud, also known as a molecular cloud, is a dense region of gas and dust located in the space between stars within a galaxy. These clouds play a crucial role in the formation of stars and planets. Interstellar clouds primarily consist of hydrogen molecules, with smaller amounts of helium and other elements. They can vary in density and temperature, with some being cold and dense enough to foster the formation of new stars and planetary systems.
Integrated Flux Nebula (IFN) refers to a type of diffuse interstellar matter that is found in the Milky Way galaxy. Unlike typical nebulae, which may consist of concentrated clouds of gas and dust, the Integrated Flux Nebula is composed of more diffuse, low-density material that scatters starlight, making it faintly visible against the background of the night sky. IFN is typically associated with the light from nearby stars, particularly those that are part of our galaxy.
High-velocity clouds (HVCs) are a type of interstellar cloud that moves at significant speeds relative to the Milky Way galaxy. These clouds are typically composed of hydrogen, and they are characterized by their high radial velocities, which can be much greater than the average motion of gas in the galaxy.
An H II region is a cloud of ionized hydrogen in interstellar space, which is typically associated with star formation. The term "H II" signifies that the hydrogen in these regions has been ionized, which means that the hydrogen atoms have lost their electrons due to the high-energy ultraviolet radiation emitted by nearby hot, young stars. H II regions are often found surrounding young, massive stars, where the intense radiation and stellar winds from these stars ionize the surrounding hydrogen gas.
HD 87643 is a star located in the constellation of Centaurus, approximately 330 light-years away from Earth. It is classified as a B-type main-sequence star, which means it is a hot, luminous star with a surface temperature significantly higher than that of the Sun. Specifically, its spectral type is B5V, indicating that it has a strong blue hue and emits a large amount of ultraviolet radiation.
HD 101584 is a star located in the constellation of Centaurus, approximately 1,140 light-years away from Earth. It is classified as a post-AGB (Asymptotic Giant Branch) star, which indicates that it is in a late stage of stellar evolution. In this phase, a star has exhausted the hydrogen in its core and has moved beyond the red giant phase, potentially leading towards becoming a white dwarf.
An Evaporating Gaseous Globule (EGG) is a type of astronomical structure that is formed in the early stages of star formation, particularly in regions of interstellar space where nascent stars are surrounded by gas and dust. EGGs are thought to consist of dense clumps of gas that are primarily composed of molecular hydrogen and dust particles. They can be relatively small and are typically located in star-forming regions known as molecular clouds.
