Combining cosmic microwave background (CMB) data from Planck satellite data,

Baryon Acoustic Oscillations (BAO) measurements and Type Ia supernovae (SNe Ia)

data, we obtain the bounds on total neutrino masses $M_nu$ with the

approximation of degenerate neutrino masses and for three dark energy models:

the cosmological constant ($Lambda$CDM) model, a phenomenological emergent

dark energy (PEDE) model and a model-independent quintessential

parameterization (HBK). The bounds on the sum of neutrino masses $M_nu$ depend

on the dark energy (DE) models. In the HBK model, we confirm the conclusion

from some previous work that the quintessence prior of dark energy tends to

tighten the cosmological constraint on $M_nu$. On the other hand, the PEDE

model leads to larger $M_nu$ and a nonzero lower bound. Besides, we also

explore the correlation between three different neutrino hierarchies and dark

energy models.
