Question: Are Castor et Pollux and Manon Lescaut composed by the same people?

Context:
Boulevard Solitude
Boulevard Solitude is a "Lyrisches Drama " (lyric drama) or opera in one act by Hans Werner Henze to a German libretto by Grete Weil after the play by Walter Jockisch, in its turn a modern retelling of François Prévost's "Manon Lescaut".
 The piece is a reworking of the Manon Lescaut story, already adapted operatically by Auber, Massenet and Puccini, and here relocated to Paris after the Second World War where, as is noted in Grove, the focus of the story moves away from Manon and towards Armand des Grieux.
 It became Henze’s first fully-fledged opera.
 The work stands out for its strong jazz influences, from a composer who had hitherto been associated with twelve tone technique.
Manon Lescaut
Manon Lescaut ("L'Histoire du chevalier des Grieux et de Manon Lescaut") is a novel by French author Abbé Prévost.
 Published in 1731, it is the seventh and final volume of "Mémoires et aventures d'un homme de qualité" ("Memoirs and Adventures of a Man of Quality").
 It was controversial in its time and was banned in France upon publication.
 Despite this, it became very popular and pirated editions were widely distributed.
 In a subsequent 1753 edition, the Abbé Prévost toned down some scandalous details and injected more moralizing disclaimers.
The Lovers of Manon Lescaut
The Lovers of Manon Lescaut (Italian: Gli amori di Manon Lescaut) is a 1954 French-Italian historical melodrama film directed by Mario Costa and starring Myriam Bru, Franco Interlenghi and Roger Pigaut.
 It is based on the 1731 novel "Manon Lescaut" by Antoine François Prévost, which has been made into films on a number of occasions.
Manon Lescaut (1914 film)
Manon Lescaut is a 1914 American silent drama film directed by Herbert Hall Winslow and starring Lina Cavalieri, Lucien Muratore and Dorothy Arthur.
 It is an adaptation of the Abbé Prévost's novel "Manon Lescaut" (1731).
 It is now considered a lost film.
Henri Larrivée
Henri Larrivée (9 January 1737 – 7 August 1802) was a French opera singer.
 He was born in Lyon.
 His voice range was "basse-taille" (equivalent to baritone).
 According to Fétis, Larrivée was working as an apprentice to a wigmaker when the head of the Paris Opéra, Rebel, noticed his talent for singing and hired him as a chorus member.
 He made his first solo appearance as a high priest in a 1755 revival of Rameau's "Castor et Pollux".
 He was particularly associated with the works of Christoph Willibald von Gluck, helping Gluck establish his "reform operas" in France.
 He found Gluck's rival, Niccolò Piccinni, less congenial but still worked with him on the premieres of operas including "Roland" (1778).
Pollux Rock
Pollux Rock ( ) is the southern of a pair of large off-lying rocks south of Vindication Island, South Sandwich Islands.
 This rock, with its neighbor Castor Rock, was named "Castor and Pollux" during the survey of these islands from "RRS Discovery II" in 1930.
 In 1971 United Kingdom Antarctic Place-Names Committee (UK-APC) recommended that they be assigned unambiguous names making each individually identifiable, and this has been done by naming the southern one Pollux Rock and the northern one Castor Rock.
Manon Lescaut (Auber)
Manon Lescaut is an opera or opéra comique in 3 acts by Daniel Auber to a libretto by Eugène Scribe, and, like Puccini's "Manon Lescaut" and Massenet's "Manon", is based on the Abbé Prévost's novel "Manon Lescaut".
 Auber's version is nowadays the least-performed of the three.
Castor et Pollux
Charles Dill proposes that Rameau had composed the 1737 opera just after working with Voltaire on the opera "Samson" that was never completed, after which he composed "Castor et Pollux" implementing Voltaire's aesthetics.
 For example, Voltaire sought the presentation of static tableaus that expressed emotion, as in the first act of the 1737 version which begins at the scene of Castor's tomb with a Chorus of Spartans singing "Que tout gemisse", followed by a recitative between Telaire and Phoebe in which the former is grieving the loss of her lover Castor, and culminating in Telaire's lament aria "Tristes apprets".
 Dill notes that in contrast, the 1754 version begins with much more background behind the story of Telaire's love for Castor and depicts his death at the end.
 The events in Act I of the 1737 version appear in Act II of the 1754 version.
 Dill claims that Voltaire was more interested in music than action in opera.
 Moreover, Dill notes a difference in the plots between in the two versions.
 In the 1737 version, the main concern is for the moral dilemma between love and duty that Pollux faces: should he pursue his love of Telaira or rescue his brother?
 Of course, he chooses the latter.
 In the 1754 version, Dill remarks that that plot is more concerned with the tests that Pollux must face: he must kill Lynceus, persuade Jupiter not to oppose his journey into the Underworld, and persuade Castor not to accept the gift of immortality.
Manon Lescaut (Puccini)
Manon Lescaut is an opera in four acts by Giacomo Puccini, composed between 1890 and 1893.
 The story is based on the 1731 novel "L'histoire du chevalier des Grieux et de Manon Lescaut" by the Abbé Prévost and should not be confused with "Manon", an 1884 opera by Jules Massenet based on the same novel.
Castore e Polluce
Castore e Polluce ("Castor and Pollux") is an "opera seria" by Francesco Bianchi.
 The libretto was one translated by Carlo Innocenzo Frugoni, from Pierre-Joseph-Justin Bernard's French text for Rameau's "Castor et Pollux".
