The boundary of the nuclear chart is studied in the relativistic continuum Hartree-Bogoliubov theory with a newly developed effective -nucleon interaction PK1-Y1. Compared with the linear prediction from the generalized mass formula, the neutron drip line is shifted outwards in light single-
hypernuclei and exhibits a pronounced shell structure in the heavy-mass region. The existence of a neutron magic number at
is suggested. Systematic trend in the heavier region shows a very weak
interaction. With
,
mesons and
tensor coupling, the bond energy of Lambdas is sharply reduced.
