A table of nuclides or chart of nuclides is a two-dimensional graph in which one axis represents the number of neutrons and the other represents the number of protons in an atomic nucleus.
 Each point plotted on the graph thus represents the nuclide of a real or hypothetical chemical element.
 This system of ordering nuclides can offer a greater insight into the characteristics of isotopes than the better-known periodic table, which shows only elements instead of each of their isotopes.
In cosmology, recombination refers to the epoch at which charged electrons and protons first became bound to form electrically neutral hydrogen atoms. Recombination occurred about 378,000 years after the Big Bang (at a redshift of "z" =  ).
 The word "recombination" is misleading, since the big bang theory doesn't posit that protons and electrons had been combined before, but the name exists for historical reasons since it was named before the Big Bang hypothesis became the primary theory of the creation of the universe.
Cluster decay, also named heavy particle radioactivity or heavy ion radioactivity, is a type of nuclear decay in which an atomic nucleus emits a small "cluster" of neutrons and protons, more than in an alpha particle, but less than a typical binary fission fragment.
 Ternary fission into three fragments also produces products in the cluster size.
 The loss of protons from the parent nucleus changes it to the nucleus of a different element, the daughter, with a mass number A = A - A and atomic number Z = Z - Z where A = N + Z.
Sir Arthur Stanley Eddington (28 December 1882 – 22 November 1944) was an English astronomer, physicist, and mathematician of the early 20th century who did his greatest work in astrophysics.
 He was also a philosopher of science and a populariser of science.
 The Eddington limit, the natural limit to the luminosity of stars, or the radiation generated by accretion onto a compact object, is named in his honour.
Post-nominal letters, also called post-nominal initials, post-nominal titles or designatory letters, are letters placed after a person's name to indicate that that individual holds a position, academic degree, accreditation, office, military decoration, or honour, or is a member of a religious institute or fraternity.
 An individual may use several different sets of post-nominal letters, but in some contexts it may be customary to limit the number of sets to one or just a few.
 The order in which post-nominals are listed after a name is based on rules of precedence and what is appropriate for a given situation.
 Post-nominal letters are one of the main types of name suffix.
 In contrast, pre-nominal letters precede the name rather than following it.
In astrophysics, the Eddington number, "N", is the number of protons in the observable universe.
 The term honors the British astrophysicist Arthur Eddington, who in 1938 was the first to propose a value of "N" and to explain why this number might be important for physical cosmology and the foundations of physics.
In music theory, limit or harmonic limit is a way of characterizing the harmony found in a piece or genre of music, or the harmonies that can be made using a particular scale.
 The term "limit" was introduced by Harry Partch, who used it to give an upper bound on the complexity of harmony; hence the name.
 "Roughly speaking, the larger the limit number, the more harmonically complex and potentially dissonant will the intervals of the tuning be perceived."
 "A scale belonging to a particular prime limit has a distinctive hue that makes it aurally distinguishable from scales with other limits."
Ashapoorna Devi (8 January 1909 – 13 July 1995) also Ashapurna Debi or Asha Purna Devi, was a prominent Bengali novelist and poet.
 She has been widely honoured with a number of prizes and awards.
 In 1976, she was awarded Jnanpith Award and the Padma Shri by the Government of India; D.Litt by the Universities of Jabalpur, Rabindra Bharati, Burdwan and Jadavpur.
 Vishwa Bharati University honoured her with Deshikottama in 1989.
 For her contribution as a novelist and short story writer, the Sahitya Akademi conferred its highest honour, the Sahitya Akademi Fellowship, in 1994.
Dunbar's number is a suggested cognitive limit to the number of people with whom one can maintain stable social relationships—relationships in which an individual knows who each person is and how each person relates to every other person.
 This number was first proposed in the 1990s by British anthropologist Robin Dunbar, who found a correlation between primate brain size and average social group size.
 By using the average human brain size and extrapolating from the results of primates, he proposed that humans can comfortably maintain only 150 stable relationships.
 Dunbar explained it informally as "the number of people you would not feel embarrassed about joining uninvited for a drink if you happened to bump into them in a bar".
Nuclear binding energy is the energy that would be required to disassemble the nucleus of an atom into its component parts.
 These component parts are neutrons and protons, which are collectively called nucleons.
 The binding energy of nuclei is due to the attractive forces that hold these nucleons together, and it is always a positive number, since all nuclei would require the expenditure of energy to separate them into individual protons and neutrons.
 The mass of an atomic nucleus is less than the sum of the individual masses of the free protons and neutrons (according to Einstein's equation E=mc) and this 'missing mass' is known as the mass defect, and represents the energy that was released when the nucleus was formed.

Question: What is the name of the limit that was named in honour of the person who was honoured by having the number that represents the number of protons named after him?
Answer: Eddington limit
