What ̯ means
In IPA, it marks the attached vowel as non-syllabic. In aɪ̯, the ɪ-like element glides within one syllable instead of making a second one. The mark changes the sequence’s syllable pattern, not the vowel quality. It follows the vowel it modifies.
A documented milestone came at the 1989 Kiel convention: a report on the revision of the International Phonetic Alphabet allowed a subscript arc to mark a non-syllabic vowel. The same glyph has other jobs in Americanist and Indo-Europeanist transcription, so the notation key matters.
A specialist phonetic mark whose meaning depends on the transcription system.
Outside IPA, check the transcription key before reading it as a glide.

1Why does this mark look detached from the letter?
It combines with the preceding character, so a font with a weak or missing below-mark anchor may place it badly. The encoded sequence still puts the mark after its base.
