  Let $k$ be a positive integer and $X_k$ be a projective irreducible nodal
curve with $k$ nodes $\{y_1,\cdots, y_k\}$. Let us denote by $X_0$ the
normalisation of $X_k$ and by $\{x_i,z_i\}$ the two pre-images of $y_i$ for
each $i=1,\dots,k$. Let us choose and fix a point $p_0\in X_0\setminus
\{x_1,\dots,x_k,z_1,\dots,z_k\}$. Consider the open subset
$B^o_k:=\{(b_1,b_2,\dots,b_k)\in\underbrace{X_0\times\cdots \times
X_0}_{k~~\text{times}}:b_i\notin\{b_j,z_j, p_0\} \text{ for }1\leq i,j\leq k
\text{ and }i\neq j \}$. In this article, we construct an family of projective
varieties $\mathcal J_k\rightarrow B^o_k$ such that \begin{enumerate} \item the
"general fiber" is the compactified Jacobian of an irreducible nodal curve with
$k$ nodes,
  \item the fiber over $(z_1,\dots, z_k)$ is isomorphic to $J_{_{0}}\times
R^k$, where $J_0$ denotes the Jacobian of $X_0$ and $R$ denotes the projective
irreducible rational nodal curve with only one node. \end{enumerate}
  We futher show that this family is topologically locally trivial over the
base $B_k$. As an application, we obtain a combinatorial description of the
mixed Hodge numbers of the cohomology groups of the compactified Jacobian of
any projective irreducible nodal curve.
